I thought maybe Richard Dreyfus would chuckle and say there isn't
any method 3. :-)

Anyway, it also can be done without AppleEvents.  

use Mac::Files;

sub get_finder_label_index { # uses Mac::Files
	my $path = shift;
	my $catinfo = FSpGetCatInfo($path) || die($^E);
	my $finfo = $catinfo->ioFlFndrInfo() or die($^E);
	my $i = ((($finfo->fdFlags + 0) & 0xE) >> 1);
	return (8 - $i) % 8; # 0 means "none"
}

sub set_finder_label_index { # uses Mac::Files
	my $path = shift;
	my $label_index = shift; # 0 means "none"
	my $i = (8 - $label_index) % 8;
	my $catinfo = FSpGetCatInfo($path) || die $^E;
	my $finfo = $catinfo->ioFlFndrInfo() or die $^E;
	$finfo->fdFlags( ($finfo->fdFlags & ! 0xE) | (($i << 1) & 0xE) );
	$catinfo->ioFlFndrInfo($finfo) or die $^E;
	FSpSetCatInfo($path, $catinfo) || die $^E;
}
