physics - make a score when objects collide

[valossa]

hello i saw a tutorial about love.physics where a ball interact with blocks, i create some other blocks and the objective of the game is fall the big block, redirecting the ball , and make it hit the blocks to fall.
But i need a little halp to make a score like this:
alwayes the ball hit the big block add a counter on the score, the game will end when the big block falls, win the player that have the lower number of hits to fall the block
