Yes. If the horn sounds before the ball enters the basket, then the ball becomes dead, since there is no longer a try involved. But if it enters the basket before the horn (or before an official's whistle creates a dead ball), then the goal counts. That would be the same as if a player got confused and shot the ball into the wrong basket. A live ball entering the basket scores as a goal.

So the tap by B1 was not a try attempt, but it doesn't matter, because the ball entered the basket, then the horn sounds. So yes, the points are awarded.

Correct.

Gotta know those scoring rules (Rule 5) and the live ball/dead ball rules (Rule 6).
