Score for old mini game file?


I would like to be able to add a score to this mini game setup to knock some pins down, it is an example from the blender game book by Delai Felinto, from around five years back.

How could I go about that? Can I use the bricks or will it require some python, if both are possible, that would be good. I think it may need programming code.

The scene is here, it is free to use. It was from 2.66, so I am using 2.76.

Thank you.
