Thanks, that makes it much more clear.

I'll see if I can hack on this.

Yes, thanks this helps a lot.

OK, understood.

This is interesting. Still using CVS Emacs (and org mode), "P" tells me
1001 for "OPEN TODO ITEMS" (2001 for #A, 1 for #C). However scheduled
TODOs which show up on a certain day all have priority -1000 regardless
of their explicitly set priorities. Is this intended?

I'll look into this.
