Sorting Wordpress posts?

Question

Ratings

Good day!
The question is, I would like to sort posts by rating (there is a plugin WP-PostRatings)
There are fields for entering values ​​from-to by rating.
But if in the loop I start to check the condition of the op rating, then the while (have_posts ()) loop is not downloaded, in yoga it says that the script has been running for more than 30 seconds. tell me what's wrong??

require($_SERVER['DOCUMENT_ROOT'] . '/wordpress/wp-load.php');
global $wpdb;
global  $wp_query, $post;

/* Sort by time */
if (isset($_POST['submit_range'])) {
  $time_from = htmlspecialchars($_POST['amount1']);
  $time_to = htmlspecialchars($_POST['amount2']);
  $rate_from = htmlspecialchars($_POST['rate_from']);
  $rate_to = htmlspecialchars($_POST['rate_to']);
}
$tables = $wpdb->get_results("SELECT `rating_postid`, `rating_rating` FROM `wp_ratings` ");

foreach ($tables as $table) {
  $p_id[] = $table->rating_postid;
  $rate[] = $table->rating_rating;
}


$i = 0;

$custom_query = new WP_Query( 'cat='.$cat );

if($custom_query->have_posts()) :
    /* Start the Loop */
    while ( $custom_query->have_posts() ) :
        if (($rate[$i] <= $rate_to) && ($rate[$i] >= $rate_from)) {
            $custom_query->the_post();
            get_template_part('template-parts/content', get_post_type());
        }
    endwhile;
endif;
// Reset Post Data
wp_reset_postdata();

it is from these fields that the values ​​\u200b\u200bare taken, then from the database I take the value of the rating from the post and check for compliance
