You could create a synthetic property that you sort on instead:
age_height_sort = db.IntegerProperty()
You can set it in a put() override:
def put(self):
self.age_height_sort = self.age*1000 + self.height_in_cm
return super(Person, self).put()
Then you can just order by that synthetic property:
Person.all().order('age_height_sort')
