I have always operated under the expectation that everyone outside one's own order is an enemy (killing = points for 'destroy tier #  enemy warriors').

If you mean OvO competition, you take points only for enemy Order units kill, but all Order member had recieve same amount points for it. I dont understand what are you mean 

Hello WWO! During the Orders War, you can attack any Town in the enemy Kingdom, but Tournament points are awarded only for destroying troops in Towns that belong to Lords of the enemy Order. 

Thanks.

That covers OvO.

Is there a chart somewhere as to whom is an enemy (giving event points), when?

I meant for any event, any time.

So,KvK?, KvKr?, none of the above (so Hunting Enemies, Supremacy, and so on.)?
