How to sort in Bitrix by property of the IB list?

Question

1C-Bitrix

Good afternoon, ladies and gentlemen.
The essence of the problem. There is an infoblock based on the complex catalog component. The list property is written in ib, it contains xml_id. The question is how to make a selection based on the TOP element component and sort them by the XML_ID of the list?
Now, if you make a selection simply by property, then there are no problems, just use (PROPERTY_MY_PROPERTY) and everything works. Tried to register PROPERTY_MY_PROPERTY-ID168 sampling does not happen. Lord tell me where to dig. I can attach the component code if needed.

The question was solved as follows: - It may be useful to someone

<?
GLOBAL $arrFilterTop;
$elementID = 2;
$arrFilterTop = array(
'PROPERTY_3' => $elementID,
);
?>

And added arrFilterTop to the component call array
