they return null as there is no status or reason in a request. It is 
same from 2003 IIRC when xlog() was introduced and used these variables.

Probably tm module can be enhanced to get these details in the script. 
t_check_status() has the functionality of checking the reply status code 
for that transaction, more or less same mechanism can be used to make 
the status available in a pseudo-variable. Or maybe moving $rr and $rs 
in tm is an option, but makes them unavailable for stateless processing 
and onreply_route[0], so might not be a good approach.

Cheers,
Daniel
