Often people do order pages due to any business rules they have for whatever reason. In reports created from such pages, the same should be shown in the same order of course.
Without that all such cases are worthless because users can't use reporting therefore.
Ideally there might be somehow a "Order" field to be used on the Page Supplier which could then be used to be reported as well and thus it might be as well used for "ordering" in the resulting table (order desc/asc etc.) together with other fields ordering or filter capabilities.
