Incidentally, all this sweating about vertex order can be unnecessary depending on how you actually handle the CR2 during rigging - the big problem is that Poser writes a new OBJ file when you create a CR2 and cuts up the geometry into separate non-contiguous spans of polygons for each body part, but I have never understood WHY this is done.  I throw away the Poser-generated OBJ and manually edit the CR2 to point back to the OBJ written out by the modeler (scaled to Poser size of course) which has no breaks at body part borders, and so vertex order is not affected.  For the rigged clothing that I've done, it has worked out very well.
