Unfortunately, it's not implemented right now, and it seems that only
Seans need it! See my post a little ways down this list about it. As it
currently stands, someone like you or I is going to have to implement it
and submit to the list before this kind of ordering is possible.
(Believe me, I have about 5-8 queries right now that could really use it.)
I'm considering trying my hand at adding it but won't have time for at
least a few more weeks due to my current project.
