It goes without saying that it is very important that children comply with time out. Otherwise they are challenging the jurisdiction of parents. I understand your motivation, but would guide you away from using scouts or basketball as the leverage. However, at the bottom line if that is the leverage you have, so be it. Take a look at Lynn Clark's book SOS Help for Parents, particularly the portion about how to respond to time out refusals (also see sosprograms.com).
