How knows the external script where to generate the BYE?

Why not use SessiontTimers (RFC 4028) ?
99% of phones replies 200 to a re-INVITE.

The problem is that you are addressing the problem in a privative way while 
there are RFC's and techniques for that. For your proposal using Session 
Timers should be the best option, but you need a UAS sending the re-INVITE's 
(at last one of both endpoinds). OpenSer cannot send it since it is a proxy 
so a B2BUA or gateway should doit.
IMHO you are addressing the problem in the wrong place (but it could work of 
course).
