Yes; you will need to use $T_rpl($hdr(...)), e.g. $T_rpl($ct):

Remember that a failure_route is a transaction failure event unrelated 
to any particular SIP reply per se, and may be triggered by things other 
than negative failure replies, such as timeouts. So, it's necessary to 
do some gymnastics to say that you want to access attributes of the 
negative reply on the winning branch.
