In the Chicago font chr(20) is the apple character that is used for the
menu name.

Try expanding the loop...

#!perl

use Mac::Menus;

 $~="OUT1";
 for $id (128..66000) {
     $menuHandle = GetMenuHandle($id);
     if($menuHandle) {
	 # $menu = GetMenuBar();
	 $flags = $menuHandle->enableFlags;
	 $data  = $menuHandle->menuData;
	 write;
     }
 }
 $~="STDOUT";


format OUT1 =
  @>>>> = @<<<<<<<<< @<<<<<<<<
  $id, $data, $flags
.

__END__

On my mac this yields...
    128 = chr(20)    -5
    129 = File       18167
    130 = Edit       44793
    131 = Window     -1
    132 = Script     -545
    133 = Alpha      23
    201 =            -1
    202 =            -1
    203 =            -1
    204 =            -1
    205 =            -1
    206 =            -1
  48981 =   L-t      -5
  49046 =   TU(      -69
  49047 =   Tqî      -9
  65664 = chr(20)    -5
  65665 = File       18167
  65666 = Edit       44793
  65667 = Window     -1
  65668 = Script     -545
  65669 = Alpha      23
  65737 =            -1
  65738 =            -1
  65739 =            -1
  65740 =            -1
  65741 =            -1
  65742 =            -1


Checking out the System file's 'MENU' resource with ResEdit it appears that
ID 49046 is the help menu.

I have FreePPP installed and it has a menubar icon just to the left of the
help menu. I'm guessing ID 48981 is for this and ID 49047 is for the far
right menu that facilitates jumping to the Finder or other open
applications.

The following code lists the 'MENU' resorces for the MacPerl application...

#!perl5

use Mac::Memory;
use Mac::Resources;use Mac::MoreFiles;

 $programPath = $Application{McPL}; # MacPerl
 &read_resource;

exit(0);


sub read_resource {
	my $refnum = FSpOpenResFile($programPath, 1);
	for $resID (128..66000) {
		$handle = Get1Resource('MENU',$resID);
		if( $handle) {
			$info = $handle->get;
			$len = unpack("\@14 C1",$info);
			$menuName = unpack("\@15 a$len",$info);
			if($menuName) { print "$resID = $menuName\n" }
		}
	}
	CloseResFile $refnum;
}

__END__

On my Mac this yields...
128 = chr(20)
129 = File
130 = Edit
131 = Window
132 = Script
133 = Editor
192 = Type
65664 = chr(20)
65665 = File
65666 = Edit
65667 = Window
65668 = Script
65669 = Editor
65728 = Type
