To whomever wonders how to switch the order of replies. This filter actually works well, just the code needs to be modified to change the array value in $query[‘order’].

function bbp_reverse_reply_order( $query = array() ) {
    $query['order']='DESC';
    return $query;
}
add_fiter('bbp_has_replies_query','bbp_reverse_reply_order');

Hope, it helps someone.

Regards,
Alex
