This is correct. I have assumed that you'd like to get 2 lines for 
tunnels: standard road and additional marking for tunnel.

As I understand, routing parameters are only valid for layer 24 (or the 
last layer in a map). I would remove road_class and road_speed from line:
highway=secondary  [0x04 road_class=2 road_speed=3 resolution 20-21 
continue]

Maybe this is the reason for routing errors?
