Answer 1

As mentioned, the proposed solution using a sortBy() callback does not work with paging.
Here is an alternative to the accepted solution:

orderByRaw()

If the appended attributes can be calculated from the fields in your query you can instead use orderByRaw(), like so:

// For example, booking percentage
$query->orderByRaw('bookings_count / total_count');
