Here's what the Cookbook offers for randomizing arrays:

<br><br># fisher_yates_shuffle( \@array ) : generate a random permutat
+ion
# of @array in place
sub fisher_yates_shuffle {
    my $array = shift;
    my $i;
    for ($i = @$array; --$i; ) {
        my $j = int rand ($i+1);
        next if $i == $j;
        @$array[$i,$j] = @$array[$j,$i];
    }
}

fisher_yates_shuffle( \@array );    # permutes @array in place
