Events Manager – Custom Category Order

Can the order of categories list for each event (when listing events) be customized?
I’ve tried combining https://www.ads-software.com/extend/plugins/order-up-custom-taxonomy-order/ but the categories order is still the same (default).
The file I’m editing is templates/placeholders/categories.php

<ul class="event-categories">
		<?php foreach($EM_Event->get_categories() as $EM_Category): ?>
			<li><?php echo $EM_Category->output("#_CATEGORYLINK"); ?></li>
		<?php endforeach; ?>
	</ul>

to

<?php foreach($EM_Event->get_categories('orderby=term_order') as $EM_Category): ?>

thanks
