Sorting of a to-many relation by eo?

Hi guys,

I hope this is easy to answer, but I need to get certainty about this:
This is my scenario:

Entity A <-->> Entity B --> Entity C, with the relations "toBs" (A-->>B) 
and "toC" (B-->C). All primary and foreign keys are no class properties.

As I have allready tested it is possible to implement a sorted array for 
the to-many relation from A to B like this:

public NSArray sortedToBs() {
     EOSortOrdering sortB = new EOSortOrdering("toC",
                                        EOSortOrdering.CompareAscending);
     return EOSortOrdering.sortedArrayUsingKeyOrderArray(toBs(), new
                                        NSArray(sortB);
}

What does EOF do with this kind of sorting? Does that mean that the 
array of Bs is sorted by the foreign keys of C? That would match my 
requirements, otherwise I have to make the foreign key a class property 
to sort by. Or is that the better way anyway?

Thanks in advance,
Susanne
