You have to split the complete processing over several EPI queries where a single query returns all elements with level=1 for a particular subfolder. You can sort_on='position' within each query. And paste the results in some way together. Nobody said that EPI would solve the problem out-of-the-box :-)

Right, so with sufficient levels you end up with a *lot* of queries. Why not just query for the whole lot and use one method that returns a (path, position) tuple for a given item, and pass that to the sort function as the key keyword? Should be a lot better performing. -- Martijn Pieters
