Sorting of listings
Listings sorting at the map sidebar controls by "Listings sidebar" metabox.
By default it sorts listings by date, but there are options to sort by title, rating, additional content fields values. When user searches listings in radius - default sorting is by distance from center point.
Some content fields types, like date-time, number, price, text string types have own setting to allow order by these fields.
Order by rating allows only when ratings addon enabled.
