ColdFusion How to pass a variable by reference

I am using a com object that takes in a string of addresses and then presorts it for mailing purposes.  

What is supposed to happen is that you call the retrieve function with the string you submit to the send function and it is supposed to give back a resorted list.  The list never gets reordered and outputs the same list I input.  I think this is because I am not passing a variable that can be passed by reference.  What can I do to get back the reordered list?  I have tried to set a variable to the function call but it says the variable is not defined after I do that.

<cfquery datasource="MHL_DB" name="addresses">
	SELECT     TOP (200) ADDRESS_LINE1, ADDRESS_LINE2, CITY, STATE, ZIP_CODE, FIRST_NAME, LAST_NAME, PATIENT_ID
	FROM       PATIENT
    WHERE      CITY <> ''
    ORDER BY   LAST_NAME
</cfquery>
<cfdump var="#addresses#">
<cfset lstAddress = "">
<cfset test = "">
 
<cfset iterations = addresses.recordcount / 25>
 
 
<cfparam name="ps" default="">

		_RecordCount = addresses.recordcount;

		addressSort = "";
	    szInput = "FLD_RECORD_ID" & _FieldDelimiter & "FLD_FIRST_NAME" & _FieldDelimiter
