Well, you'd have to define the function inside the sortMoves function, as 
it is where the variables exists.

def sortMoves(board, table, ply, moves):
    def sortKey(move):
        return getMoveValue(board, table, ply, move)
    moves.sort(key=sortKey, reverse=True) return moves

Wouldn't that make it create the callable at each call?
