Sorry after going through my email again I realised it was ambiguous.
When I say it doesn't work, I don't mean Org throws an error when
tags:nil is set. The preprocessing gets skipped.

To restate my intentions more clearly; I want to preprocess headlines
that match the tags list "tag1|tag2" during latex export irrespective
of how the tags: option is setup. If this is not possible by a tags
match, what are my alternatives?

Thanks a lot. :)
