Change the display order of listings

You’d need to write a custom function to remove dollar signs and commas from the price field, save it as a new meta field, and then sort by that.

Here are some old functions, specific to Genesis Framework, that could work but you would need to update and customize:

function clean_listing_prices() {

	$args = array(
		'numberposts' => 1,
		'post_type'   => 'listing'
	);

	$listing_posts = get_posts($args);

	$clean_price_field = get_post_meta($listing_posts[0]->ID, '_clean_listing_price', true);

	if ( !empty($clean_price_field) ) {
		return;
	}

	$args = array(
		'post_type' => 'listing',
		'posts_per_page' => -1
	);

	$lq = new WP_Query($args);

	while ( $lq->have_posts() ) : $lq->the_post();

		$price = genesis_get_custom_field('_listing_price');

		$clean_price = preg_replace('/[\$,]/', '', $price);

		$id = get_the_ID();

		update_post_meta($id, '_clean_listing_price', $clean_price);

	endwhile;
}

function wpl_ordered_listings_content() {

	clean_listing_prices();

	$args = array(
		'post_type'    => 'listing',
		'numberposts'  => -1,
		'meta_key'     => '_clean_listing_price',
		'orderby'      => 'meta_value_num',
		'order'        => 'DESC',
		'status'       => 'active'
	);

	$active_listings = get_posts($args);

	$args['status'] = 'pending';

	$pending_listings = get_posts($args);

	$args['status'] = 'sold';

	$sold_listings = get_posts($args);

	echo '<h2 class="taxonomy-title">Active Listings</h2>';
	wpl_iterate_posts($active_listings);

	echo '<h2 class="taxonomy-title">Pending Listings</h2>';
	wpl_iterate_posts($pending_listings);

	echo '<h2 class="taxonomy-title">Sold Listings</h2>';
	wpl_iterate_posts($sold_listings);

}
