What would you need a module for? Simply encode your ruleset into a comparitor subroutine, and use the sort built-in: 
sub compare_lines {
  # return a 1,0,or -1 depending on which of $a or $b is larger
}

my @lines = <FILE>;
sort compare_lines @lines;

Remember, sort is an abstraction of sorts :) If you can express, in code, whether $a is >, <, or == $b, you can use sort.
