Do you know where your variables are?

I would say that the idea of an $ERROR variable is good in concept (similiar to the perl variable $!). However, if this is in a module then I think abstraction should be the key.

This way I can have the script decide ...

It's important, I agree, to let the script decide; however, the script shouldn't have to handle the code to decide.

For example, there could be a warn method in your module (or error, etc.), that accepts a variable and then chooses the appropriate level to warn the calling program (or to die() itself).

One benefit to this approach is that you can easily have the warn level in your program localized -- and contrary to handling it all yourself, changing what it is would be as simple as changing a parameter.

This, of course, assumes that the module takes an OOP approach (which I'm biased towards myself).
