Comment (by wonderboymusic):

 Because these values will eventually be passed to `WP_Query`, only valid
 values will make it through `->parse_orderby()`, so I think this strict
 check is unnecessary here.

 The only place `sanitize_sql_orderby()` is used is in the gallery
 shortcode - it's used in the playlist shortcode too, but I only added it
 there because it was in gallery.
