I added that to one of my models just to test, and it works fine for
me (adding ids since I have no quantity field). I'm still on .96 and
using postrgres though. Sorry I don't have an answer, hopefully
someone else will!

I'd be more worried about pulling all the item(s) info over just to
get a sum than the counting, but if you need to display item info
anyway it probably doesn't matter at all. Especiallly if you used
select_related() on the getting the order in the first place.
