Let's say I have a subtree, of review materials, for example. I would like
to randomize the order of the elements. I would like to have the option to
randomize the subtree in some different ways:
1. sort the members of one subtree that is a list, randomly.
2. sort all the headlines, randomly.
3. sort the subtrees randomly, and the lists within each sub-subtree
also randomly, ad nauseum.
I have written a sort routine in elisp. It's been many long years ago, but
I remember that the basis support for writing sorts is pretty general.
Suppose I had time to do this. What would I need to look at?
Of course, my need is today, to sort review materials for my students in
random order.

You can use the custom function in the sort command to supply org-sort
with a random number. When calling org-sort, note the function option
presented:
,----[ C-c ^ (org-sort)
| Sort %s: [a]lpha [n]umeric [p]riority p[r]operty todo[o]rder [f]unc
| [t]ime [s]cheduled [d]eadline [c]reated
| A/N/T/S/D/C/P/O/F means reversed:
`----
You could thus write a quick function, using whatever amount of
randomness you want:
--8<---------------cut here---------------start------------->8---
(defun my-org-random-sort ()
(random 1000))
--8<---------------cut here---------------end--------------->8---
Then on the appropriate subtree/table/list, type:
C-c ^ f my-org-random-sort

Sorry this response comes a little to late. :)
Best,
Matt

That is excellent. Not too late, at all. This ability to sort by a
function is excellent: presumably one could use a soundex algorithm!
Thank you,
Alan

Actually I just found out that C-c ^ f random RET works fine too!

Thanks for the tip. Much more elegant.
Best,
Matt
