FIBA rules say this (I didn't check but I think it's like this)

a goal in your own basket is scored as usuall and noted on the other teams captain.
An INTENTIONAL goal is a violation and the other team gets the ball in the side.

I've been about a team who once scored intentional own goalds, the coach told his player (shouted out) that they should score so the diffrential weren't that bigged. If I had been the ref (I was in the audiance) I would have tossed him right away, I've never seen a more unsportsmanlike thing ever.
