The two scenarios (service road layer 0, corridor layer 1 and service road layer -1, corridor layer 0) are equally correct. There's no such thing as "grade level" when it comes to the layer tag. But...yes: renderers should respect the layer tag, on all objects. It sounds like Mapnik only respects it in combination with certain other tags, such as bridge=yes and tunnel=yes.
