Custom Fields value array & search

Range search can be done as follows:

$true_args = array(
	'meta_query' => array(
		array(
			'key' => 'price',
			'value' => array( 1000, 3000 ),
			'type' => 'numeric',
			'compare' => 'BETWEEN'
		)
	)
);
$true_query = new WP_Query( $true_args );

But how can you do a search if the field value looks like this:

a:3:{i:0;a:1:{s:5:"price";s:3:"150";}i:1;a:1:{s:5:"price";s:3:"856";}i:2;a:1:{s:5:"price";s:5:"78988";}}

It is written several prices. Sampling should be done by anyone, or even be the first.
