Org mode sort issue

[jl256]

 

In my org file I declare:

#+PRIORITIES: 0 9 9

Say I have a list of sub-headings under a parent heading:

TODO [#0] Bob
TODO Tim
TODO [#1] Percival

I was until recently using emacs 26.1 with org mode 9.1.9.

If I did a Sort region/ children C-c ^ [p]riority on the parent heading I would get:

TODO [#0] Bob
TODO [#1] Percival
TODO Tim

Which is what I want.

Now I am using the same file in emacs 29.4 with org mode 9.6.15 and the same sort command gives:

TODO Tim
TODO [#0] Bob
TODO [#1] Percival

Which is not what I want and I believe is not how things should work.

I posted about this a while back at

https://emacs.stackexchange.com/questions/82838/org-mode-sort-region-children-sort-order-has-changed

and this behaviour was reproduced by someone else and they suggested I report this as a bug.

Thanks and regards.
