Allow Books Search to be sorted by Rank

Robert Kelbe

Logos prioritizes resources by Rank, not Rating. The passage guides list commentaries by Rank, not Rating. For that reason, I am not always as diligent to use the Rating system as the Ranking system.

However, when I search by library, I can only sort by Count, Title, and Rating.

Please consider adding the ability to sort by Ranking. Thank you!
