How can I get "Time/Costs" account IDs with QBXML?

Question

I'm running this query:

<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="14.0"?>
<QBXML>
<QBXMLMsgsRq onError="stopOnError">
<InvoiceQueryRq>
<IncludeLineItems>1</IncludeLineItems>
<IncludeLinkedTxns>1</IncludeLinkedTxns>
</InvoiceQueryRq>
</QBXMLMsgsRq>
</QBXML>

And I get this invoice line which is an expense created with the "Add Time/Costs" button in Quickbooks Desktop.

<InvoiceLineRet>
<TxnLineID>8E-1343336207</TxnLineID>
<Desc>License and Title</Desc>
<Rate>315</Rate>
<Amount>315.00</Amount>
<ServiceDate>2012-07-26</ServiceDate>
<SalesTaxCodeRef>
<ListID>80000002-1343060273</ListID>
<FullName>Non</FullName>
</SalesTaxCodeRef>
</InvoiceLineRet>

With most invoice lines, there's an item associated with it and I can get the account(s) associated with the item. I want to get the account ListID that's associated with this invoice line, as with other invoice lines. I can get the account name with a GeneralDetailReportQuery, but not the ID, and that report is much harder to work with as I'm importing Quickbooks data into another system.

How can I find the accountID for lines like this?
