The actual code I wrote to sort and rank...But this doesnt have the code to accomodate the input data of the form shown above and hence it fails unless I can pre process the data and then run the script. Here is the actual code; 
#!/usr/bin/perl
# Rank array data in accordance with their P-values
# Script author: AR, 2007.


my $pvalues_file = $ARGV[0];    
my $MAX_TOP_ENTRIES = 20;

open PVAL, "< $pvalues_file" or die "Error: Can't open $pvalues_file: 
+$!";

my %arrays;
my @profile_names;

while (my $line = <PVAL>) {
    chomp $line;
    if ($line =~ /^ARRAYS/) {
        my $hdr, $i;
                ($hdr, @profile_names) = split("\t", $line);
        for $i (0 ... $#{@profile_names}) {
            $profile_names[$i] =~ s/^\s+//;
            $profile_names[$i] =~ s/\s+$//;
        }

        } else {
                 (my $array_name, @pvalues) = split("\t", $line);

          for $i (0 ... $#{@profile_names}) {
            $arrays{$array_name}{$profile_names[$i]} = $pvalues[$i];
        }
    }
}


foreach $array (keys %arrays) {
    my $top_count = 0;
    print "$array\t";
    %pvalues = %{$arrays{$array}};
        @profiles_sorted = sort { $pvalues{$a} <=> $pvalues{$b} } ( ke
+ys %pvalues );
    foreach $key (@profiles_sorted) {
        $top_count++;
            if ($top_count <= $MAX_TOP_ENTRIES) {
                  print "$key:$pvalues{$key}\t";
        }
    }

      print "\n";
}
