That;s ok also.

avoid using IF with hardcoded values - you will have to restart each 
time you want to add/delete/change something there. Better use something 
like dialplan module to do the translation between the quality and the 
group.

No need for priority - simply make a rule for prefix 72 with 2 GWs (A 
and B) and use weights - set the wight flag for the rule and as gw_list 
put "A=50;B=50" - See the DR doc on that.
