That drives me nuts! Minimax search would eliminate bad lines of play whenever 
a refutation is found. A good opponent would not play badly, and the quantity 
of possible bad moves should not affect the evaluation of good moves - but that 
seems to be what MC does, averaging out all moves regardless of whether they 
are known to be good,  have been refuted, or are of indeterminate status.

What am I missing?

If it only did one playout you would be right, but imagine the following cases:

case 1: White wins by .5 x 100, Black wins by .5 x 100
case 2: White wins by 100.5 x 91, Black wins by .5 x 109

the method that takes into account score would prefer the second case even 
though it has a lower winning percentage that may be represented by the fact 
that white is making an overplay for instance.  Obviously this is just one 
example, but there are many cases like this and overplays tend to be 
priveledged in a sense I would suspect with this kind of algorithm.
