How to set if meta_value is lower < than other meta_value in a get_posts array?

Use this type of code :

$args = array(
    'author'        =>  $publisher_info->ID,
    'post_type' => 'post',
    'tax_query' => array(
            array(
                'taxonomy' => 'type',
                'field'    => 'slug',
                'terms'    => array( 'campaign' ),
            )
        ),
    'meta_query' => array(
            'relation' => 'AND',
            array(
                    'key' => 'status',
                    'value' => 'active',
                    'compare' => '='),
            array(
                    'key' => 'B',
                    'value' => '1',
                    'compare' => '!=')
            )
);
$data = new WP_Query($args);
