Sorting can be done by specifying the sort expression when building the query. Paging is not currently supported. This is something I have spent a lot of time working on but have not gotten the code to a point where it is ready for release. Perhaps things will calm down a bit at work over fall/winter and I can invest more time into tackling this issue. Until then your best option is to either use an ObjectQuery with the QueryHelper to build the paging query manually or get the generated sql by compiling the OPathQuery and do some string parsing to build a paging version.
