Comment(by miqrogroove):

 sirzooro, I'll have to give you some suggestions at this point because I
 don't have any slick tools for injecting tag strings.

 Go to the wp-includes/post.php file and start stubbing-in debug commands
 to the function wp_insert_post().  Specifically, look at the value of
 $tags_input and $tax_input right after the extract() is done.  You might
 be able to use something like this:

 {{{
 error_log(print_r($tax_input, TRUE));
 }}}

 Figure out, at that point in the code, has the tag been truncated or
 modified in any way?  This should give us a pretty good idea of how much
 string sanitizing has been done before the tags are passed to the Taxonomy
 API.
