Opponent DC'd and I got no points

Well, I Just played a game where I drushed my opponent so hard that when I reached Castle Age with 30 xbow he was still feudal with 100 food and 4 skirms. Thing is, as soon as I hit Castle Age, the game gave me a prompt saying my opponent disconnected blah blah, and then I got the "You Won!" at the end of the game. Still I got no points, and I've had dced before due to connection issues and did lose points. So how come this is posible? (ratings were even)
