How to sort Wordpress posts by ACF custom field?

Question

WordPress

The post has a custom field of type Number.
You need to sort the posts, the field of which falls into the desired range.

$args = array(
    'posts_per_page' => 5,
    'cat' => $current_category->term_id,
    'meta_query' => [
        'relation' => 'AND',
        [
            'key' => 'size',
            'value' => 50,
            'compare' => '>'
        ],
        [
            'key' => 'size',
            'value' => 100,
            'compare' => '<=',
        ]
    ]
);
$query = new WP_Query($args);

But there are no such sweats, although there should be.
