log() does not support select values, use xlog instead which accepts 
xl-formatted strings. They can contain selects and avps, just start them 
with percent sign: "this is and avp: %$myavp, and this is a select: 
%@ruri.user".

You can use them in the conditional statements, for example to check 
whether or not the called party starts with +:
if (@ruri.user =~ "^\+") ...

Lots of functions accept selects as parameters, for example the second 
parameter of lookup_domain():
lookup_domain("$td", "@ruri.host");

Have a look at etc/sip-router-oob.cfg for examples.
