Well we have different subcategories of alien space bats but ASB covers a wide range of things e.g. ASB because aliens get involved, ASB because you haven't focused on all the factors in a scenario, etc.

A scale would be quite complex as there are many different reasons for ASB-ness but you can easily say what is more probable and improbable. Its do-able.
