Since r1257 Extbase respects the 'sorting' and 'sorting_foreign' fields from the TCA, but it seems to me that it's not possible to manipulate the sorting from within Extbase (without writing SQL).

I've solved sorting by rewriting the ObjectStorage in the way i'd like 
the related objects to be sorted. Iterating over the "old" ObjectStorage 
applying the objects in the order i'd like to achieve to the new 
ObjectStorage. After that i replace the assigned ObjectStorage with the 
"sorted" one.
I don't know if there is a cleaner way to do this - but it works for me.
