Sounds quite doable so far.

I'd say - in this case: Just forget about collision detection. 
You know the coordinates of the puck, you know the coordinates of your
net, just calculate if the puck is in or not. Whith clever use of an
offset table, you can even calculate if it's within a round shape, for

***   	-> 0
  **   	-> 2
   **  	-> 3
   **  	-> 3
   **  	-> 3
  **   	-> 2
***    	-> 0

Of course you don't need to do the zeros, but the general idea should be
clear now, hopefully :-)
