It looks good. Could you send it on this ML as a patch so I can comment
it more conveniently?
Since you want to comment I guess you want the patch in the e-mail body
rather than attached. Here goes nothing.

Subject: [PATCH] Add priority inheritance
* New org-use-priority-inheritance defcustom to toggle inheritance.
* org-get-priority now takes a pos and implements inheritance.
* org-get-priority-function can make use of inheritance by returning t.
* org-agenda-fix-displayed-priority ensures inherited priority is
visible.
* Updates where priority is used so that inheritance is respected. As
a side effect, org-get-priority-function is now more widely
respected.
