if you want to short event by ascending order then simply replace desc with asc in below code in sc_event-list.php file
private function html_events( &$a ) {
// specify to show all events if not upcoming is selected
if('upcoming' != $a['actual_date']) {
$a['num_events'] = 0;
}
$date_filter = $this->get_date_filter('all', $a['actual_date']);
$cat_filter = $this->get_cat_filter($a['cat_filter'], $a['actual_cat']);
if( '1' !== $this->options->get( 'el_date_once_per_day' ) ) {
// normal sort
$sort_array = array( 'start_date DESC', 'time DESC', 'end_date DESC' );
}
else {
// sort according end_date before start time (required for option el_date_once_per_day)
$sort_array = array( 'start_date DESC', 'end_date DESC', 'time DESC' );
}
$events = $this->db->get_events($date_filter, $cat_filter, $a['num_events'], $sort_array);
