You could try the "from" operation(which is minus with the inputs swapped) in a merge node to comp shadows from vray without inverting/multiplying.
as a side note composting raw passes can lead to some edge artifacts as (i believe) the renderer combines these passes on a per sample basis and averages the samples to create the final image whereas in comp the final anti aliased passes are combined on a one sample per pixel basis this may create slight differences in edges.
