 Well, for reference, here is Matt Cutts on sculpting:

 Sorry, wp_rel_nofollow() is for the pre_comment_content filter, so it
 escapes in preparation for the comment to be inserted into the db. You'd
 need to use this, which steals a line from wp_rel_nofollow() and uses its
 helper callback:

 {{{
 add_filter( 'wp_generate_tag_cloud', 'my_nofollow_tag_cloud_example' );
 function my_nofollow_tag_cloud_example( $text ) {
    return preg_replace_callback('|<a (.+?)>|i',
 'wp_rel_nofollow_callback', $text);
 }
 }}}

 Again, I feel this doesn't belong in core for various reasons mentioned
 above.
