That reminds me, I originally had a really bad feeling about writing a script

I appreciate that. But like all lethal weapons, responsibility for their use lies in the hands of those who use them. ;-)

the Finder isn't updating this volume's modification date.

This is just puzzling to me.

I simply wouldn't trust Finder for something like this.

As long as we're changing the specification,

I don't see that we're changing 'the specification'. The task is to accurately find the last time the volume was accessed. We're discussing different ways to do that, is all.

and when the volume was starting to get full, this daemon would erase
the oldest files.

What do you think about this idea?

Back to the task at hand - I think you've got the answer more or less wrapped up in your script, it's just a matter of getting the last access time right. I'm working on something else at the moment, but will have a further think about this later today or tomorrow. I'm sure there's a simple solution in bash somewhere, it's just avoiding me right now. Will do some digging in my books later.
