Your problem is perfectly suited to a solution involving the application of quantum regular expresion dynamics (QRED). Your code as it stands attempts to match each type of emoticon in turn; thus, it is jumping the gun and testing the match before the match actually occurs, but the test changes the match and forces it to happen in a certain way -- which isn't what you want. Instead, you want to write your regex so that it will match either type of emoticon; thus, as it matches, it enters a superposition of states wherein it is simultaneously both a smiley and a winkie. *Then* you test which it is, and at that point the waveform collapses to a particle and you get your answer, which you can use to decide which replacement text to use.

In other words, do what Ed Halley said.

{my$c;$ x=sub{++$c}}map{$ \.=$_->()}map{my$a=$_->[1];
sub{$a++ }}sort{_($a->[0 ])<=>_( $b->[0])}map{my@x=(&
$x( ),$ _) ;\ @x} split //, "rPcr t lhuJnhea eretk.as
o";print;sub _{ord(shift)*($=-++$^H)%(42-ord("\r"))};
