Dear Alex, thanks for reminding me. I have now fixed the problem (SVN revision 111233). Updating the single file ./includes/export/SMW_Exporter.php should suffice. I have not found a bug report about this; if there is one then it would be good if you could point me to it s I can close it.
The reason for the problem was that no sortkeys had been stored for subobjects in RDF. But sortkeys are necessary to properly order results (even if the order is arbitrary, this is important for displaying, e.g., the "first" 10 results). The order will now be based on the parent page name, followed by the subobject name (whether set by the user or selected internally by SMW or some extension). The sortkey will be stored properly for all future updates now; this means that existing data will need to be rewritten to get the required information (by editing the affected pages or by using SMW's update feature on Special:SMWAdmin).
