Use a solenoid to dump 9 balls (it's usually 9) in a trough. Watch the scoring hole switches for points. In many of these games, dropping a ball in any hole other than the lowest one causes it to roll past all the switches for the lower holes - and all those switches are in parallel. Count the pulses and display the score. Another, still lower (ball count) switch in the game indicates when a given throw is over.

Is that an African or a European orange?
