Is this more what you were thinking of?

#!/usr/bin/perl

use warnings;
use strict;

my %hours;

while(<DATA>) {
    next unless $_ =~ /\w+/;
    my @F = split;
    if ( $F[2] =~ /(\d{2})\:\d{2}:\d{2}/ ) {
        $hours{$1}{value} += $F[3];
        $hours{$1}{count}++;
    }
}

for ( sort { $a <=> $b } keys %hours ) {
    print "Sum   at $_ hours is ", $hours{$_}{value}, "\n";
    print "Count at $_ hours is ", $hours{$_}{count}, "\n";
}
