wp_query order properties first by number last string

I have a properties website where pulling properties from API. There are prices and strings in the price field. I want to show the properties with number first. Now there are showing modified on first position. So when price is changed to "Sold" its on first position. So first properties with number all other like "sold" and "sale agreed" last. this is an easy job. i found solution but its not working so dont bid more than 10$!
