When ordering a query by meta_value, if you are using a numeric meta_value, do this:

$args = array( 
	'post_type' => 'msd_contest_entry', 
	'numberposts' => -1, 
	'meta_key' => 'Votes',
	'orderby' => 'meta_value_num'
	);
$items = get_posts($args);

Otherwise:

$args = array( 
	'post_type' => 'msd_contest_entry', 
	'numberposts' => -1, 
	'meta_key' => 'Votes',
	'orderby' => 'meta_value'
	);
$items = get_posts($args);
