A quick check of the code (I am no coder so excuse if I have this wrong) in the-events-calendar/views/list.php and the loop appears not to specify any order – it just looks for posts and takes them in order!
<?php if (have_posts()) : ?>
<?php $hasPosts = true; $first = true; ?>
<?php while ( have_posts() ) : the_post(); ?>
