The Score generates with the following, simple system:
Mole Paired * 10 - Hearts Missed - Moles Missed and this is for every difficulty the same, so a perfect Score would be 100. I know it got a few disadvantages and you can also have a negative Score, but I wanted it challening. I may change it later...
