Your best bet is to get all the shortest paths from each of the vertices in B using get.all.shortest.paths and then count how many of these paths pass through A "manually". Note that there could be multiple geodesics originating in B and going to some other vertex v, and it can happen that _some_ of these paths pass through v and others do not; in this case, you have to add the appropriate fraction to A's betweenness score. This could be a bit tricky to get it right but not impossible.
