To follow up on the idea John Huebner mentioned to use the acf/update_value filter.

First you will need the field key of the field you have named “mc_sort_id”.
To get that go to the Field Group admin page, click the “display field key” button in help dropdown, then copy the “mc_sort_id”-field key (looking something like this “field_1231313”).
Then you should be able to use the following code in your functions.php file.
Just remember to replace “my_repeater_field” with the name of your repeater field and also replace “field_xxxxxxxx” with the field key you copied above.

function my_acf_update_value( $value, $post_id, $field  ) {
	$mc_sort_id_FIELD_KEY = 'field_xxxxxxxx'; // Set this to the field key of your field called "mc_sort_id".
	
	$order = [];

	foreach ( $repeater as $i => $row ) {
		$order[ $i ] = $row[ $mc_sort_id_FIELD_KEY ];
	}

	array_multisort( $order, SORT_ASC, $value );
	
	return $value;
}
add_filter( 'acf/update_value/name=my_repeater_field', 'my_acf_update_value', 10, 3 );
