 Basically, a meta_value of '0' is ignored in meta queries, It bases it on
 empty(), so a meta value being "empty" is ignored.

 This mainly comes into play for numeric comparisons, ie. field >= 0 (do
 not want -50 etc)

 Code: [http://core.trac.wordpress.org/browser/trunk/wp-
 includes/meta.php?rev=17170#L423 Line 423] change from empty() to
 strlen()?

 Core includes a [http://core.trac.wordpress.org/changeset/17088#file2
 hack] to work around this already
