See the documentation of die:

If an uncaught exception results in interpreter exit, the exit code is determined from the values of $! and $? with this pseudocode: 
        exit $! if $!;              # errno
        exit $? >> 8 if $? >> 8;    # child exit status
        exit 255;                   # last resort

And likely, $! is set from some other operation that your script (or Perl) performed. So you can't rely on a specific exit code if your script dies.

If you need something really specific, you could install your own handler via either an END block or a $SIG{__DIE__} handler (perlvar).
