I am considering adding the second parameter to km_append_branch() for
backward compatibility reasons.
Alternative is to use $branch(...) variable to set the q after you
called append branch:
http://www.kamailio.org/wiki/cookbooks/3.3.x/pseudovariables#branch_attributes
Q has to be set via integer value, with range from 0 to 100 (0.1 would
be 10).

The core functions were added before the existence of cfg variables,
they take only static strings as parameters. The way to do it is via
assignments.
