The correct way to set the content type and disposition is (untested) 
print "Content-type: archive/zip\n" .
          "Content-Disposition: attachment; filename=$filename\n\n";
binmode STDOUT;
$zip->writeToFileHandle( \*STDOUT, 0 );

There's a few points here:
  1. The correct way to set the content-disposition is with the filename= part but without the quotes around the filename (I think).
  2. With your current code you are trying to append the result of writeToFileHandle to your string. I think you mean ";" instead of "."
  3. writeToFileHandle expects a filehandle reference, not a string corresponding to the name of a filehandle.
  4. You should set binmode on a filehandle before writing binary data to it.
Give that a shot.
