Can someone explain the tournament scoring system?

In UK we use:

For every 10% of your Attrition saved 1 point
For every 10% of enemy attrition taken 2 points

Sack enemy camp without being broken and own camp not sacked +5 points
Break opponent +5

I think the question may relate to the on-line game? If so you've posted in the wrong place.
