Global Posts Ordering – can't get it to work

I’m having problems getting the Global Posts Ordering plugin to work. I set up the functions file correctly, and I think I’m using get posts according to the plugin directions. The only thing I can think of is that I’m using additional code in my loop to parse get_posts and only return the image attachments, but that shouldn’t affect the order that the posts are returned right?

It’s a nice plugin with a nice looking interface, I’d love to get it working. Any help would be appreciated. Thanks!

Here’s the part of my loop where I call get_posts

<?php
	$args = array(
		'order' => 'ASC',
		'orderby' => 'menu_order',
		'post_parent' => $post->ID,
		'post_status' => 'inherit',
		'post_type' => 'attachment',
		'post_mime_type' => 'image'
	);
		$images = get_posts($args);
			if ($images) {
				$count = 1;
					foreach ( $images as $id => $image ) {
					if( $count === 1 ) {
					if ( !in_category( _x('link', 'link', 'twentyten') ) ) {
						$img = wp_get_attachment_thumb_url( $image->ID );
						//$link = get_permalink( $post->ID );
						$link = wp_get_attachment_url($image->ID);
						$title = get_the_title();
						print "\n\n" . '<div id="intcont" class="alignleft"><a href="' . $link . '" rel="lightbox[reed]" title="' . $title . '"><img src="' . $img . '" alt="" /></a></div>';

								};
							}
							$count++;
						}
					}
				?>
