Ah! Thanks kindly for the info! Sounds like I'm doing weird/odd stuff.
What can I say, I'm just a cog. :p
I'd looked at the <asminfo> task, but my boss wants me to update the
file in place, as opposed to recreating it each time. I don't suppose
there's a way to load an existing assemblyinfo file into the <asminfo>
task? Otherwise, the <script> tag looks like the way to go.

wow ! - I've never seen the nant expression language used in quite that
way.
I'd seriously consider using either:
- the AssemInfo task
(http://nant.sourceforge.net/release/latest/help/tasks/asminfo.html) or
- an inline script using the script task
(http://nant.sourceforge.net/release/latest/help/tasks/script.html)
<asseminfo> allows you to do what you are after using a built in task
and with <script> you can use any .Net code which will be much easier (
and clearer ) than trying to use NAnt as a procedural programming
language.
