I agree with your expectation that a1-4 should be the same.  Why do you
expect that b1-4 would be?  Shouldn't tags-todo consider only none-DONE
todo items, in the same spirit as m versus M?  In other words, I'd
expect b1 and b3 to be empty by definition.

It's helpful if you provide a minimal test file.  I've tried to come up
with one that I think should capture what you're describing.

--8<---------------cut here---------------start------------->8---
* TODO h1                                                               :PROJ:
* TODO h2
* DONE h3                                                               :PROJ:
* DONE h4
* TODO h5                                                               :PROJ:
SCHEDULED: <2020-06-14 Sun>
* TODO h6
SCHEDULED: <2020-06-14 Sun>
* DONE h7                                                               :PROJ:
SCHEDULED: <2020-06-14 Sun>
* DONE h8
SCHEDULED: <2020-06-14 Sun>
--8<---------------cut here---------------end--------------->8---

With that, a1-4 all show:

    scratch:    TODO h2
    scratch:    TODO h6

That doesn't match what you're seeing.  I'm testing with 706970 checked
out, the commit you reported in your follow-up message.

For b2 and b4, I see

    scratch:    DONE h4
    scratch:    DONE h8

b1 and b3 are empty, which I think is expected given the tags-todo type.
