What happens if a figures pushes to KO?

In a multiplayer match who gets the points?

What happens when a figure is KOd as a result of proximity mines?

I think the controller of the last fig that damaged it would get the points.
I know that doesn't cover all the options but I don't know the answers for the rest of them.

From the Icons Rulebook, page 32:

kinda unfair cause I beat up magog till he had 2 clicks left and my friend shot with a random for 1 damage and Magog was knockedback into a proximity mine and at the end of the turn was blown to smithereens.

I did 9 clicks of damage and I don't get any points? How does that work?

Life is unfair, however if the your friend had OK'd Magog by doling out 2 damage you'd still be out the points for the OK so it still seems "fair"
