Summary: do_routing sort parameter does not accept AVP

Initial Comment:
Note
- Problem encoutered on 1.7.2 but is certainly present in previous version. 
- in 1.8.0, dynamic routing has changed a lot and function parameter are not the same

The problem: 
In the opensips script, I tried to use the following code ( using AVP for the group and sort parameters ):
if (!do_routing("$avp(routing_group)","$(avp(sda_sort)")) {

This is working well for the group parameter but not for the sort parameter. When starting opensips, I get this error:
ERROR:core:fixup_uint: bad number <$(avp(sda_sort)>


Looking at the code, in $SRC/modules/drouting/routing.c for the fixup fonction of drouting "fixup_do_routing(void** param, int param_no)", the code for the "sort" parameter is:
        if (param_no==2) {
                /* sorting algorithm */
                return fixup_uint(param);
        }

It seems that the function can only handle a regular string like "0" or "1" and not AVP ( while the group parameter can with the fixup function using much more code to handle the group parameter and expanding AVP ).
