Here is a routine that works. Due to your request, I've added it to the
win32lib.

-----------------
global function getMenuPosn(integer pID)
    -- Given an ID of a menu item, this returns is zero-based
    -- position within its parent menu.

    -- Known bug: Doesn't work on submenus yet.

    atom lWnd
    atom lCount
    atom lPosn
    atom lID

    lPosn = -1

    lWnd = getHandle(pID)
    lCount = w32Func(xGetMenuItemCount, {lWnd})
    if lCount > 0 then
        for i = 0 to lCount - 1 do
            lID = w32Func(xGetMenuItemID,{lWnd, i})
            if lID = pID then
                return i
            end if
        end for
    end if

    return lPosn

end function

You can get this from the MSDN site but be prepared for a HUGE download.
