The reorder tool does what its name suggests - you give it the name of an OBJ mesh (other than the one you have open in UVMapper) and it tries to reorder your mesh so that it can be a successful morph for the second mesh. However, since your morphs apply correctly, it can't be vertex order and it certainly isn't the wrong number of vertices. Maybe it's a problem with UVM 2? I can try your UVS through 3.2 if you want.
