Why don't you like to use t_on_failure? You have to, you cannot check
the status of the response processing the request. So your config should
look like (not much deffering from your version :-) 

if (uri="sip:0 at .*"){
   sethost("192.168.10.1");
   t_on_failure("1");
   t_relay();
}

failure_route[1] {
if (t_check_status ("480"))
{
# final response received, we need to create new branch
   append_branch();
   sethost("192.168.10.2");
   t_on_failure("2");
   t_relay();
   break;
}
}

failure_route[2] {
#your second gateway failed too....
}
