Put your US # on your reservation but save your boarding passes and all paperwork because you will probably have to file a missing miles request. Apparently this comes from the VS side as they will not issue partner miles without documentation.
I will say that I've flown VS twice in the last six months and my DM account was credited quickly and without manual intervention both times so I wouldn't over-worry about that.
