Billy,

If you block a shot and it goes into your own basket that means that the basket you have been trying to score on all game long. This is not a typical 3 point shot vs. a 2 point shot argument. You cannot shoot a 3 point shot into the other team's basket. And a blocked shot is not a try.

If you really need a reference, look at 5-2-1 where it says:

A successful try, tap or thrown ball from the field by a player who is located behind the team's own 19-foot, 9-inch arc counts as three points. A ball that touches the floor, a teammate inside the arc, an official or another goal from the field counts two points for the team into whose basket the ball is thrown. See 4-5-4.

Now since a blocked shot is not a try, there is no support to give three points.

I think you might have misunderstood the question.

Peace
