descr is a user-controllable attribute also in the RIPE and AFRINIC regions, so I think that it would be safer to move this code to a dedicated function like query_crsnic or else anybody could cause infinite loops.
Then make_ip_del.pl and make_ip6_del.pl would need to be modified to invoke that function for queries for APNIC networks.

Also, you need to check that the record has a mnt-by: APNIC-STUB attribute to be sure that this is a real redirect.
