I don't do a lot of this kind of work, but as an interested party with sunday spare time, I think the problem here is that you're scoring anything other than the first picks.
If you just look at first picks, Newbie HBase wins 3 to 1. If for some reason Newbie HBase was in a 2/2 split with Mapreduce and KIR (flip James's top 2 votes), you then take into account 2nd rankings, which in this case means Newbie HBase wins again.
I don't believe you ever want to take into account someone's griefer vote, too much potential to game the system with no benefit to the group as a whole.
