E1 9.2 - Running order of basic preferences

Is there any documentation that details the sequence in which a collection of basic preferences will be evaluated? 

For example we are running the type 06 basic inventory commitment and the type 39 basic product allocation (branch) preferences (amongst others). Testing appears to show that the product allocation preference is executed before the inventory commitment preference but I've not been able to confirm that this is as expected.

I think I understand correctly that if advanced and basic preferences are being used then the advanced preferences will be evaluated first and that the running order of the advanced preferences can be controlled in P4070? But when it comes to the basic preferences what if anything controls the sequence they are evaluated in?
