Score value is randomized in a way that favors high scores:

rand = random.uniform(0.0, 1.0)
new_value = self.sanity * value +
            (1.0 - self.sanity) * rand * self.max_value

After this algorithm sorts moves with these new_value's and we select
new top move.

sanity=1.0 -> original ordering
sanity=0.0 -> completely random
