I am trying to sort this by distance (km)... All works but I just can't seem to get this to happen 
open(FILE, "herbalarea.pl") || die "I can't open that because: $!\n";
     while(<FILE>) {
   chop;          @all = split(/\n/);

   foreach $line (@all) {
   local($hStoreID, $hStoreLatitude, $hStoreLongitude) = split(/    /,
+ $line);

$lat2 = $hStoreLatitude;
$lon2 = $hStoreLongitude;
$lat1 = $lat1a;
$lon1 = $lon1a;


       # Notice the 90 - latitude: phi zero is at the North Pole.
       @L = (deg2rad($lat1), deg2rad(90 - $lon1));
       @T = (deg2rad($lat2), deg2rad(90 - $lon2));
       $km = great_circle_distance(@L, @T, 6378);


#-------HERE IS THE PROBLEM---------#
@km=sort {$a <=> $b} (@zip_dist);
$km = (@zip_dist);
#-----------------------------------#

if ($km < $distance)

{
       $match = 1;
$count ++;

   $area = "$hStoreName <BR> $hStoreAdd <br>  $hStoreCity, $hStoreProv
+ $hStorePC\n";
       
$rounded = sprintf("%.1f", $km);
print "
$area $km
\n";
}
