Sorting shortcode

In the documentation, I see the custom sorting codes as follows:
[es_my_listing sort=”recent”] – displays recent listings first
[es_my_listing sort=”oldest”] – displays oldest listings first
[es_my_listing sort=”featured”] – displays featured listings first
[es_my_listing sort=”title”] – displays listings in alphabetic order`

Is there a code for sorting by price?
This is the current code I’m using but does not work:
[es_my_listing status=”SOLD” layout=”3_col” sort=”highest_price”]

-PS- The example page does list the listings by the price but I entered the listings in the order of the price so the highest-priced listing is the newest to hack the issue but not feasible for the long run.

The page I need help with: [log in to see the link]
