Comment (by dglingren):

 Thanks, @tyxla, for your update. I removed the check and did a bit of
 testing. Without the check, you can specify multiple fields, e.g.,
 orderby="author date title".

 Since the shortcode parameters are passed as strings, the one thing you
 can't do is specify column-by-column ASC/DESC values.

 It seems like a bit of enhancement to the /wp-includes/query.php function
 parse_orderby() would be able to support syntax like orderby="author date
 DESC title", applying ASC or DESC to the column name that immediately
 precedes it. I can't think of a drawback to this addition offhand.
