To explain further, Qt 3 is a single unified library that requires a GUI 
to be available in order to do some many basic operations (such as 
creating an off-screen pixmap or doing most other graphics operations) 
even when the application has not created any windows.

Qt4 lifts that restriction and allows an application to start up in a 
pure console mode that doesn't require a GUI.

Scribus could still support command line scripting in Qt 3, it'd just 
have to be run from a session that has a DISPLAY (under UNIX) or is 
enabled to interact with the user (Windows). Note that on UNIX you can 
do this with the Xtest server or the Xvfb server for VNC, so the output 
need not actually _go_ anywhere.

Of course, getting Scribus to the point where it can do useful things on 
the command line is a lot of work too. Craig B. has been working on that 
for a while amongst other stuff, and there's still more to do.

Batch PDF export should not actually be _too_ hard (last time I looked 
anyway) if someone wants to get in there and focus on that. It'll still 
involve some significant refactoring of the PDF output path to avoid 
direct access to the options dialog controls by the PDF export code. 
I've done bits and pieces toward this, but last time I checked there was 
still quite a bit more left.

Anyhow, Qt4 is _extremely_ nice (I've been using it quite a bit lately) 
and it'll make this stuff easier, to there's probably not too much 
incentive to leap onto the automation stuff until that transition is done.
