This one sounds kind of fun.
We discussed directed graphs other issues like: https://github.com/SouthForkResearch/pyGNAT/issues/7
I think all we have to do here is the same kind of thing and then compare adjacent nodes to see if there's a problem then flag all the problems.
I found an interesting tool built for shapefile networks called nx_spatial. Looks like he wrote a script related to finding flow directions. Might be worth checking out.
I think I've found a way to find stream segments (i.e. graph edges) with an incorrect flow direction.

Each stream reach show know which adjacent reaches are upstream.
