This is a good example to use the Schwartzian Transform. 
#!/usr/bin/perl

use strict;

my $string;
while( <DATA> ) {
    $string = $string . join " ", $_;
}

my $test = join "\n",
           map { $_->[0] }
           sort { $a->[1] <=> $b->[1] }
           map { [$_, (split)[9]] }
           split( /\n/, $string);

print $test;
