Just found here http://support.intel.com/support/network/sb/cs-005897.htm that

By default, Intel adapters strip the VLAN tag before passing it up the stack.

In this case WinpkFilter receives 802.3 frame without VLAN tag and there is no way to access it without additional efforts. Even if you do the modifications mentioned on that page to turn off stripping tag then I’m not sure that TCP/IP stack will be able to process these packets with extended header normally.
