For that AI, I would suggest creating a random number to make the AI's paddle vary rather than being +-2. The AI's paddle is currently still "aligned" to the ball, its just offset by a number. Not really an AI when you are cloning the coordinates.

For the scoring system, make sure you added up the dimensions properly. It is very hard to make sense of all the different pixels plastered in the code. How big is the actual playing area?
