a new version of scribus has been released today. Copying and renaming the ebuild for scribus-1.3.3.1 builds everything successfully. Maybe it's also possible to bump scribus-1.3.3.1 to stable. There are no outstanding bug reports for it and it has been in testing since 10th of April. There are a lot of improvements since the 1.2.x series and the 1.3.3.x series don't seem to be marked as development releases anymore. 1.3.3.2 is merely a bug fix release so it could be bumped to stable after 30 days.
