Trying to create a Subroutine to sort array based on any column numerically when my array is having both characters and numercis Below code doesnt seem to work 

#!/usr/bin/perl

$objd=sprintf "%10.0f %10.0f %10.0f %10.0f %10.0f", "15","4","5","6","
+7";
$objd2=sprintf "%10.0f %10.0f %10.0f %10.0f %10.0f", "8","9","10","11"
+,"12";

push @numbers,$objd;
push @numbers,$objd2;

sub sort_array
{
    @unsorted_array = @{$_[0]};
    $col_2sort = $_[1];

        ## Implementing Schwartzian Transform algorithm to sort in fas
+test way
    @sorted_array=  map { # Get original line back
                      $_->[0]
                  } sort { # Compare input fields
                      $b->[$col_2sort] <=> $a->[$col_2sort]
                  } map { # Turn each line into [original line, input 
+field]
                      [ $_, (split " ", $_)[$col_2sort] ]
                  } @unsorted_array;
}

printf "UN-Sorted Array\n";
foreach my $line ( @numbers ) {
printf "$line\n";
}

@sorted_array= sort_array(\@numbers,2);
printf "\n\n\n";
printf "Sorrted Array\n";
foreach my $line ( @sorted_array ) {
printf "$line\n";
}
