If I understand the question, you want to change the mean value of a random function to a given value, right? This is a linear transformation, and it is very simple to implement:

$val = old_random_function() - $old_avg + $new_avg;

or, create a new function:

sub new_random_function { old_random_function() - $old_avg + $new_avg }
