I'm not sure this ever worked correctly. But it didn't matter because sorting
happens at ndb.Model.put() time. So sorting here on object retrieved from the DB
is effectively useless.

Ah, ok. So if they're sorted in the DB, then there's no need to sort them at all
here and I can just delete this loop.
