Well, it is more about lower level design and may not be necessary in the first plugin framework implementation , but one approach comes to mind:
Based on configuration one can build dependency matrix.
Its rows and columns represent all desired plugin implementations, say, A B C D. Now, if A depends on B the location (A,B) gets the value 1, otherwise 0. And so on. The next step is to create a priority vector based on this matrix and pass it to the initializer.
Just an idea.
Thanks,
Zhanna

How is init order established?
