Comment(by aaroncampbell):

 I'd love to see this allow for IN as well as BETWEEN.  The diff I'm
 attaching does just that.  It also allows in or between to be passed in
 any case (between, BETWEEN, BeTwEeN, etc) and uses the WordPress standard
 `preg_split('/[,\s]+/', ...);` to make sure it works as expected.

 Now it also works like this:
 {{{
 get_posts( array( 'meta_key' => '_test', 'meta_value' => '5,8',
 'meta_compare' => 'between') );
 get_posts( array( 'meta_key' => '_test', 'meta_value' => array(5,8),
 'meta_compare' => 'BeTwEeN') );
 }}}
