How are the contests actually being scored in terms of where the fighters place in the standings?

Im gonna assume there is a league table with the 6 fighters in and the natural procedure will be after the 3 fights putting the top ranked guy in with the 4th ranked and 2nd v 3rd.

Does abraham move top of the rankings due to the knockout or is he level pegging 1st with froch now?

showtime should really be explaining this a bit better...
