Um, no? I don't recall ever hearing anything like that. Additionaly, even if that was true, at two regionals I've only seen a 10 pt ball rolling around maybe twice. I actually got to shoot one once (during a practice round) but our goal was already overflowing and it just went right through the poles.
Go to usfirst.org- download the game and scoring documents- that should help clarify the game's scoring.
