I recently saw a bug for this specific function, but I don't think that
has anything to do with this (http://trac.wordpress.org/ticket/4549)

It should be <?php wp_tag_cloud('number=42&orderby=count'); ?>

It touches number with the function wp_parse_args ( line 1288 in
wp-includes/functions.php ) and again in wp_generate_tag_cloud.

I do not know much this topic (hell, I don't even know what that
function does, nor the wp_parse_args (except merging two arrays)), so
you should listen to what others say. Neither do I know PHP to well (and
if someone can tell me why they use $args = '' as parameters in a
function I will be very happy.
