I just tried samtregar's suggestion with a gash C .exe that exits with the return code of the argument (don't ask). Thought it might be helpful if I posted the code:
use warnings;
use strict;
use Win32::Process;
use Win32;

my $code = 'C:\\Perl Modules\\Win32\\ExitCode\\Debug\\FileClose.exe';
my $ProcessHandle;

Win32::Process::Create (
   $ProcessHandle,            
   $code,        
   qq("$code" 1289),  # Note syntax because path has an embedded space
+        
   0,                    
   NORMAL_PRIORITY_CLASS,        
   ".") || die "Oops: $^E";

$ProcessHandle->Wait(INFINITE);   

my $ExitCode;
$ProcessHandle->GetExitCode($ExitCode);

print "Exit code: $ExitCode\n";

The perl program correctly reports an exit code of 1289. By the way, I tried the C program using ExitProcess and exit() (C RTL) and both worked. The MSDN gives the return type in ExitProcess as UINT (unsigned int), which is 32 bits.
