If you're trying to block the update, ProcessUpdates is too late (all
it lets you do is make more changes and push messages back up to the
user).

If you want to actively block the user, look at
RT-Extension-MandatoryOnTransition.  It uses the BeforeUpdate callback
in Ticket/Update.html to set skip_create and push onto @results.  You
can clone that functionality to the Default callback in
Ticket/Modify.html.
