Hi What you have found is one of weaknesses in the Fedora RDF structure. The normal way, btw, is to have each of the pages declare their page number in a literal relation.
Remember, a RELS-EXT relation does not have to be to another object, it can be literal. so something like <rdf:RDF> <rdf:Description rdf:about="info:fedora/ThisObject"> <myNS:hasPart rdf:resource="info:fedora/TheIssue"> <myNS:pageNr>15</myNS:pageNr> </rdf:Description> </rdf:RDF> When you do a triple store query, you will then be able to sort based on the PageNr. Note, this approach does not guarantee that no the pages will have distinct numbers in an issue.
