Comment (by mtredinnick):
It doesn't make sense mathematically. This isn't a personal preference
thing. It's the fact that you cannot order an SQL query based on multiple
results. You're trying to turn an ordering on individual items into an
ordering on sets of those items and there's no canonical way to do this.
The fact that the results you get are somewhat aligned with what you are
hoping for is accidental and not at all guaranteed in general.
At some point, Django will raise an error when you try to specify such a
field in an ordering clause; it just doesn't do so yet.
