Would something like this work?

highway=motorway [0x01 road_class=4 road_speed=7 level 6 continue]
highway=motorway & oneway=yes   [0x10f01 level 6]
highway=motorway & oneway!=yes   [0x10f02 level 6]

Then style 0x01 with no style (so nothing is drawn) - 0x01 would be used 
for the routing information.

Then style 0x10f02 as plain motorway and 0x10f01 as motorway with arrows.
