Hi Charlie,
I assume you are setting the resource in the call to Ngl.polyline. It's a bit counter-intuitive perhaps but tfPolyDrawOrder is a resource belonging to the plot object that you draw the polyline on.
I think you can set it either for the resource argument of Ngl.contour_map or you can use an explicit Ngl.set_values on the map object return value of Ngl.contour_map.
We may be able to make this more convenient in the future by extracting from the Ngl.polyline res argument behind the scenes and then setting it for the plot argument.
