MDT Script ZTILangPacksOnline.wsf bug

I try to install the language pack online in the sccm tasksequence with the MDT step.
But in the log file i see:

"Language Packs can only be installed from within Windows Vista, Windows Server 2008, or later
OSes"

Please look at the code:

If iOSVerMajor < 6  or oEnvironment.Item("OSVersion") = "WinPE" then
			oLogging.CreateEntry "Language Packs can only be installed from within Windows Vista, Windows Server 2008, or later OSes", LogTypeError
			Main = Success
			Exit Function
		End if

The script looks at the first number of OSVersion and Windows 10 begins with 10.0.xxx .
So 1 < 6 and the language pack get not installed.

Is this a known Issue?

Could this be fixed with the next MDT release, please?

Thanks!
