Presumably because the gap exists in the current system, and the current system is optimized for the current scoring function. Changing the scoring function will cause the system to rebalance into a new steady state.

Although, there is no clear reason why the new steady state would not be female dominant or evenly split, but if I were to take a bet, I would bet that the new scoring function will still hold existing bias because the problem starts much earlier.
