Event Sorting on SlideDeck 2

They also have this code on their site which shows you how to do custom sorting for the slider:

/**
 * Modify sort method for WordPress post based SlideDecks
 *
 * @param array $query_args The Array of query arguments passed to WP_Query
 *                          (http://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters)
 * @param array $slidedeck The PHP Array that describes the SlideDeck being rendered
 *
 * @return array
 */
function slidedeck_posts_slidedeck_query_args( $query_args, $slidedeck ) {
    // Check to see if the SlideDeck being rendered is ID 1451
    if( $slidedeck['id'] == 1451 ) {
        // Set the orderby value to use the "meta_value"
        $query_args['orderby'] = "meta_value";
        // Set the meta_key to use to "event_date", this should be the meta_key name you want to sort by
        $query_args['meta_key'] = "event_date";
        // The direction you wish to sort (ASC|DESC)
        $query_args['order'] = 'ASC';
    } 

    // Always return $query_args, even if you aren't modifying it or you will break things
    return $query_args;
}
// Hook into the slidedeck_posts_slidedeck_query_args filter and specify a priority of
// 10 (default) and receiving 2 query arguments, so we get information about the SlideDeck
add_filter( 'slidedeck_posts_slidedeck_query_args', 'slidedeck_posts_slidedeck_query_args', 10, 2 );

I would like to know how to tie that code into the event Start Date on The Events Calendar.
