I need to sort the below hash build numericaly by it's keys,

I wouldn't want:
  1, z49535L10.txt, 24.7413310185185
  10, test.avi, 24.5892824074074
  100, Copy.7z, 24.5827546296296
  2, here.avi, 24.5753703703704
  20, z42034L10.txt, 24.7494328703704

  but, rather, the correct counting order.

#current
chdir('\temp');
opendir(DIR,'\temp');
@files= readdir(DIR); 

$count=1;
for (@files) {

	$daysold  = -M $_;
	$hash{$count}="$_, $daysold";
	$count++;

}

# sort keys numerically?
while ( ($key, $value1, $value2) =  each( %hash)) {
     print "$key, $value1, $value2\n";
}
