Wont show two posts with same custom date

I am ordering posts with a custom date, but it wont display two posts with the same custom date and display in date order. I really need help with this please. Below is the code that is ordering the date:

<?php ; }  elseif  ( is_page( 'Older People' ) || '186' == $post->post_parent ) {	?>

<?php
$agenda = get_posts('&category_name=older-people&numberposts=-1&order=DESC'); ?>
	<?php
// an empty array
$date_order = '';
if( $agenda ) : ?> <?php  foreach( $agenda as $post ) : setup_postdata( $post ); ?> 

<?php 	$custom_date = get_post_custom_values('fund_dead');
	if (isset($custom_date[0])) {
	$evento = strtotime($custom_date[0]);
	} else {
   $evento = strtotime($post->post_date_gmt);
			}
	$date_order[$evento] = $post->ID;

// now the array contain key as date and post ID as value
	 ?>

	<?php endforeach;  ?>
 	<?php endif; ?>

<? // and the second

// order the date in the custom field
ksort($date_order);

foreach ($date_order as $key => $val) {
 query_posts('p='.$val);
global $more;
$more = 0; 

// the second Loop
while (have_posts()) : the_post(); ?>

<div class="divide"></div>

<div class="event-main">

<a href="<?php the_permalink() ?>"><h1><?php the_title(); ?></h1></a>

<?php
   $eventDate = get_post_meta($post->ID, 'fund_dead', true);
   $today     = esc_html_e( date( '' , strtotime( $fund_dead ) ) );
   if($eventDate == $today) { ?>

     <h3>Deadline: <span id="event-list"><?php $date = 'Ongoing' ; echo($date); ?></span> </h3>

  <?php } else { ?>

      <h3>Deadline: <span id="event-list"><?php $fund_dead = get_post_meta($post->ID, 'fund_dead', true);
esc_html_e( date_i18n( 'l, F jS, Y' , time( $fund_dead ) ) ); ?></span> </h3>

  <?php } ?>

<h3>Eligibility: <span id="event-list"><?php $fund_elig = get_post_meta($post->ID, 'fund_elig', true);
echo apply_filters('',  $fund_elig); ?></span> </h3>

<a class="event-more" href="<?php the_permalink() ?>">Read More</a>

</div>
<div style="clear:both;"></div>  <?php endwhile; ?>

 <?php	} ?>
