rmetfd on "Wordpress posts alphabetical"

I'm trying to get posts working alphabetically.

Only thing is, I'm showing a list of child posts on the page using the following code:

<?php
	$pageChildren = $wpdb->get_results("
		SELECT *
		FROM $wpdb->posts
		WHERE post_parent = ".$post->ID."
		AND post_type = 'page'
		ORDER BY menu_order
	", 'OBJECT');

	if ( $pageChildren ) :
		foreach ( $pageChildren as $pageChild ) :
			setup_postdata( $pageChild );
			?>
			<?php $imagethumb = get_post_meta($pageChild->ID, 'image-thumb', $single = true); ?>

<div id="solutionbutton">
<div id="centerbutton">
		<img src="<?php echo $imagethumb; ?>" />
		<h4><?php print '<a href="' . get_permalink( $pageChild->ID ) . '">' . get_the_title( $pageChild->ID ) . '</a>'; ?></h4>
		</div>
		<div id="entry">
			<?php echo excerpt(13); ?>
</br></br>
			<a href="<?php echo get_permalink($pageChild->ID); ?>">Read More...</a>
		</div>
</div>
		<?php
		endforeach;
	endif;
	?>

Nothing I've tried is getting it to work alphabetically!
