please investigate underlying cause, this should throw an exception if the transformation is not supported

Based on testing, seems like

| makeresults count=1 | eval "estimates(a_b)"=1 | rename '"estimates(a_b)"' AS e_a_b 

works. I think the issue is caused by eval not stripping the quotes given for the field, but rename does do it, resulting in the error.
