you are confusing python expressions and path expressions.
You can do either of these:

       <td tal:content="item/absolute_url">123</td>

OR

       <td tal:content="python:item.absolute_url()">123</td>

If you have not already done so, you should read the Zope Book
online chapters about Page Templates and Scripting.

"this did not work" is not very clear. It works for me.

The result is a list of tuples of the form (id, object)
so maybe you are not handling the result correctly.
