Unable to get address fields from salesorder from "Custom" address

I have a sales order with multi line shipping enabled.
When the order is saved with a "Custom" address, the address does not get added to the Customer record and I am unable to fetch the address fields.
I still get an internal id for the Custom address. Is there any way to fetch the custom address fields?
I tried looping thru the customer address sublist as well as searching address (code below) with no luck.

Any help is greatly appreciated.

 var itemShipTo = nlapiGetLineItemValue('item', 'shipaddress', i);  nlapiLogExecution('DEBUG', '####itemAddress:'+i, itemShipTo);  if(itemShipTo){      var filters = [new nlobjSearchFilter('internalid', null, 'anyof', itemShipTo)];      var columns = [new nlobjSearchColumn('address1'),          new nlobjSearchColumn('address1'),          new nlobjSearchColumn('city'),          new nlobjSearchColumn('state'),          new nlobjSearchColumn('country'),          new nlobjSearchColumn('zip')];      var addressSearchResults = getSearchResults('address', null, null, columns);
