wp_enqueue statement conflicting

Not sure why People Lists worked previously but not anymore, but if one of the wp_enqueue lines is removed from people-lists.php, the plugin again works fine. This solution is listed in the support forums here. For some reason, a javascript conflict is happening with jquery-ui is loaded by this plugin, though that didn’t happen in the past with the same theme, so it must be a change that happened in WP core. (The forums would suggest that it came about somewhere around version 3.5.2.)
