For the time beeing, use
NDragIt to move the frame. In the future, I have plans to work on a mod, called Aid Me!, that would be battle ground and PvP utilities, including what you wanted, yet I do not currently have time nor resources presently, as I am a college student.
bgTrack, though I have not used it, might be what your looking for. I have not tried
DopiesPvPTracker, yet it could be what your looking for. I have used
HKCounter in the past, it logs stats from bg to bg; I do not know if it is working in 3.0.2, however I recommend you try that first.
