Change the “orderby” arg to ‘orderby’ => ‘meta_value’ and then specify ‘meta_key’ => ‘presenter’ (rather than ‘meta_value’ => ‘presenter’). This will order the query results by the meta_value of ‘presenter’.
It sounds like you’re trying to also query posts with a specific ‘presenter’ value. If so, add to the $args array:
'meta_query' => array(
array(
'key' => 'presenter',
'value' => '"' . $presenter_value . '"',
'compare' => 'LIKE',
)
)
