Add filters to order recordings by track number first when displaying an album's content

Tracks in this collection must be displayed following a certain order. The student in charge of this project has used track numbers in order to display them correctly. When they look up the collection using key words "Ocaso de los soles" and filtering results by collections, the order is displayed correctly. However, when they access the collection as a whole (see link above), tracks do not follow this order. I propose two possible solutions for this. Solution 1: filter recordings by track number first, then by track name for all albums. Solution 2: add filter options to the album display template so that users can choose how to order tracks.

This is how tracks are displayed at the collection level:

This is how tracks are displayed at the search bar level filtering results down using keywords "Ocaso de los soles" (and the way it should be displayed at the collection level as well):

An even better idea would be to add filters above, so that it could be ordered in ascending/descending order by track number, by title, and so on.
