I know it's been a while since this has been posted, but I thought I'd bring light to what is happening. Since I know this confuses a lot of people. Essentially when you war, and you beat someone, it takes into account how many people fought, won, and lost.
So if you have 1 person win a war 7-0 you may only get like 5 clan points, but if you have 3 people. Win 2,2, and 3 games you could get like 9 and if you have 7 different people win you could get like up to 10. You could also have 1 person win a bunch, and a bunch of other people lose, and still get full points or more, because you had more people participate. You could get 5 points for only winning one match and losing a war if you had enough people fight, theoretically.
However, the point system is pretty much null now with the clan levels, and what a more important is actually winning as you get more experience for a win. So regardless of wether it is misleading or mot it doesn't really matter, that having been said, I do think it's hanged now to show the actual scores of the war.
