A kid with Asperger's often has such a narrow range of interests that letting them choose isn't a good idea; and they need structured social activities to develop the ability to connect with others. Our experience with DS8 is that often things we "make" him do become things he enjoys after some time has gone by.
My feeling is to insist that he do one social group (scouts, 4H, something analogous) and one other activity (in our family it's music, could be a team sport or something else). If he wants to quit scouts, make sure something else is in the mix to keep him socially active with peers.
