Ok, we're nearly there.. but I have one mysterious problem I cannot understand:

I inserted this code:
    my @names_and_rates = map { [ $_->{name}[0], $_->{data}[0] ],[ $_-
+>{name}[1], $_->{data}[1] ] } @alldata;
    @maxref = sort { $b->[1] <=> $a->[1] } @names_and_rates;
    foreach (@maxref[0 .. 2] ) { print $_->[0], "\t\t", $_->[1]*8, "\n
+<BR>";    }

But got this: 
file      rate
          384434.306056 
          191966.35544 
          122524.077608
So clearly I'm missing the {name} parameter. So, I figured what I needed to do was flatten out the @alldata array a bit. I used this:
Update Fixed a minor typo in the code below... 
    my @maxtmp = sort { $b->{data} <=> $a->{data} } @alldata; 
    my @names_and_rates = map { [ $_->{name}, $_->{data}->[0] ],[ $_->
+{name}, $_->{data}->[1] ] } @maxtmp;
    @maxref = sort { $b->[1] <=> $a->[1] } @names_and_rates;
    foreach (@maxref[0 .. 2] ) { print $_->[0], "\t\t", $_->[1]*8, "\n
+<BR>";    }

..And it worked!
Now I just need to know a more effective way than that first sort to flatten out the array, since the first sort operation (to @maxtmp) is wasted - but I didn't know how to use the map command to do the same thing.

Any hints?!? Update 2: Thanks to arturo for the simple fix, below: 
    my @names_and_rates = map { [ $_->{name}, $_->{data}->[0] ],[ $_->
+{name}, $_->{data}->[1] ] } @alldata;
    @maxref = sort { $b->[1] <=> $a->[1] } @names_and_rates;

#this next bit just prints the top three
    foreach (@maxref[0 .. 2] ) { print $_->[0], "\t\t", $_->[1]*8, "\n
+<BR>";    }
