Battleground scoring

[Waky]

I'm attempting to recreate an addon that tracks your killing blows, honorable kills, etc. in a broker frame. Right now I'm using the following API to find these values:

GetNumBattlefieldScores()
GetBattlefieldScore(i)

These work perfectly for what I'm trying to do except for ONE thing; they won't seem to update unless I open and close the PvP stats frame. Is there a way to get these to work without having to open/close the PvP Stats frame?

Thanks in advance!
