Bite Tibor's score in that situation would be 5-6*, not 6-7; but this would not affect your end result. All we need to know is whether there was a two- or three-way tie. Either way, OP is through to the knockout stage, it's just in which half he ends up...
* 0-0 draw, 1-4 defeat, 1-1 draw, 3-1 win.
