First, you cannot set a 0-index map vertex, maxscript indexing starts with 1. Second, in your code you use in one branch verts selected in unwrap modifier - why would you use polyop.methods after that (since that won't update/change unwrap at all, only the baseobject) and not unwrap methods instead?
