Django - How does order_by work?
order_by can have multiple params, I think order_by('score', '-create_time') will always return the same queryset.
I'd like to know how Django's order_by works if the given order_by field's values are same for a set of records. Consider I have a score field in DB and I'm filtering the queryset using order_by('score'). How will records having the same values for score arrange themselves? 
Every time, they're ordered randomly within the subset of records having equal score and this breaks the pagination at client side. Is there a way to override this and return the records in a consistent order?
I'm Using Django 1.4 and PostgreSQL.
