I want a Custom Post Type Relationship (Lecturer) to load in a particular order: alphabetically ascending by custom field value (lecturer-surname).

  

    $course_id = get_the_ID();
    $related_lecturers = toolset_get_related_posts(
		$course_id, // get posts related to this one
		'course-lecturer', // relationship between the posts
		'parent', // get posts where $writer is the parent in given relationship
		100, 0, // pagination
		array(
            'post_type' => 'lecturer',
            'orderby' => 'meta_value',
            'meta_key' => 'wpcf-lecturer-surname',
            'order' => 'ASC'
        ), // How was his surname, again…?
		'post_object',
		'child'
	);

Hello,

Thanks for the details, I can login into your website, will update here if there is anything found

The function toolset_get_related_posts() is different from WP_Query, the "meta_key" should be put insider into argument "$args".

In your case, you can try the WP_Query, like this:

$course_id = get_the_ID();

$query = new WP_Query( 
	array(
		'post_type' => 'lecturer',
		'numberposts' => -1,
		//new toolset_relationships query argument
		'toolset_relationships' => array(
			'role' => 'child',
			'related_to' => $course_id,
			'relationship' =>'course-lecturer'
		),
		'meta_key' => 'wpcf-lecturer-surname',
		'orderby' => 'meta_value',
		'order' => 'ASC',
	)
);
$related_lecturers = $query->posts;
