Maybe you consider that version 3 of the terse output is only used since Fio version 2.0.3!
Before that I think that IOPS are not in the terse output (http://freecode.com/projects/fio/releases/341331).
In the current Debian (http://packages.debian.org/squeeze/fio) and Ubuntu LTS releases (http://packages.ubuntu.com/precise/fio) the Fio version is before 2.0.3 and therefore the terse output is not of version 3.

As Jens said, you can also switch to JSON format instead.
So maybe you are stuck to use Fio from the git repo to have a newer version.
