I have an Interrail pass. At the Interrail website I can only book a seat. At the Autrian railways I can only book a complete ticket, including trainfare + sleeping place.
Question
How do I book a sleeping place in the train from Zurich to Budapest?

Did you select Interrail under the Discounts. That is how you book couchette or sleeper reservation on ÖBB. (It should be arround 44€ for a couchette reservation, but the reservation price is dynamic)
ÖBB certainly sell pass reservations online. As always, Seat61 explains how to book:
