Your example works with Matheamatica v9.0.1.0 on my Mac:

$Version

9.0 for Mac OS X x86 (64-bit) (January 24, 2013)

FindShortestPath[Graph@{
    Property[1\[DirectedEdge]3,EdgeWeight->100],
    Property[1\[DirectedEdge]2,EdgeWeight->2],
    Property[2\[DirectedEdge]3,EdgeWeight->3]},1,3]

{1,2,3}

FindShortestPath[Graph[{
    1\[DirectedEdge]3,
    1\[DirectedEdge]2,
    2\[DirectedEdge]3},
    EdgeWeight->{100,2,3}],1,3]

{1,2,3}
