Let me see if I can explain the scoring to you. Basically each league has 12 teams(at least that's what I have noticed in my two years playing) and you get points for Batting Average, Home Runs, Runs Scored, RBI, Stolen Bases, Wins, Strikeouts, Saves, ERA and WHIP.
The max amount of points per category is 12: That means that if you are in 1st place in one category, you get 12 points, second place gets 11, third place gets 10 and so on. The sum of all the points from all the categories gives you a total score and that's what determines your placement in the league, at least under Routissiere scoring rules.
