in reply to Scientific notation problem

It depends mostly on the method you use to sort. A plain string sort, which is the default, will be easily confused because it tries to sort the numbers alphabetically.

Here's what I used, and it worked: 
#!/usr/bin/perl

my @nums = (2.3e+4, 4e9, 7e-9, 4e-3, 4e-14, 4.4e-14, 4e-13);

foreach (sort {$a <=> $b} @nums)
{
        print "$_\n";
}

    I did use something similar. I said: 
    foreach(sort byval keys %index)
{
...
}

sub byval
{
   return ($score{$a} <=> $score{$b})
}

    Is there a way to force numerical evaluation?

      That should do it, except that you're evaluating %score on the keys of %index, which may just be an error in your example, or something that should work, but isn't clear from your example.

      You can "force numerical evaluation" with the <=> operator.
