Hello!
I’d like to start using dr Wozniak’s tasklist idea [1] in Org. He’s
the original author of spaced repetition and SuperMemo.
It’s about assigning values ($) and time (hrs) to each task. Then,
priorities ($ divided by hrs) can be calculated, and then you do the
tasks with the highest priority; effectively, spending your time in
the most valuable way. (That is if you assign the value and time
correctly, but it can be learned.)
Is there anything like that implemented? I couldn’t find anything.
If not, how hard would it be? Where would it be best to start?
Thank you!

I do not know of anything like this, but it should not be difficult to
implement. You could store $ and time as properties in a headline, and
then write a custom sort function for use with org-sort-entries that
computes the priority and sorts in the direction you want. I do not know
how you would integrate that into the agenda, but I assume it is
possible.

If you don't care about integrating into the agenda, this could be
quite easily implemented in an org table.

Aloha kakou,
I started to find the above idea pretty interesting, and so I did a
small proof of concept coding to implement it. (Certainly this could be
done a lot better but I just wanted to try it out.)
I'm going to work with the idea for a little while to see how well it
helps in sorting through tasks.

;; Implement supermemo style task list processing via org-mode tables.
;; Usage: M-x org-tasklist-add and follow the prompts. If you use it a
;; lot, tie it to a function key or something fast and useful.
;; The task table file, tasks.org, goes to the org default directory,
;; and is created if it doesn't yet exist.
;; Tasks have an input value (in any units you like), time (in any
;; units you like) and a description. Priority is then calculated as
;; value/time and the table is sorted from highest value at top to
;; lowest value at bottom.
;; This is /not/ integrated with the org-mode agenda. That is keeping
;; with the philsophy explained by Dr. Wozniak, that tasks with
;; time-constraints should be avoided if possible and scheduled
;; separately when they cannot be avoided. (This seems like a fair
;; amount of wishful thinking.) But in any case, high-priority or
;; high-value items can be manually added to the agenda if so
;; desired. (I don't yet have an automated function for this.)
;; I think the task table could contain many items, none of them (yet)
;; urgent. It may be a way of prioritizing future work (chosing the
;; most valuable work), which later gets projectized (perhaps) and
;; scheduled. What the table can surely do, which I think is of much
;; merit, is screen out low value projects and tasks that simply
;; aren't worth doing, either on their own merit or compared with
;; higher payback items.

[Being nit-picky here: :-) Wozniak is the author of SuperMemo and he has
made many changes/adjustments to the algorithms for optimal spacing, and he
is probably the one responsible for making this thing popular but, as he
himself makes clear, the spaced repetition phenomenon is something
documented in the psychological literature long before SuperMemo]
