Yes such a test would work.  However, the creation and automatic  
maintenance of .octaverc might get messy. Especially since users will  
commonly edit it.

In any event, some options are

(1) Modify savepath.m to create a .octaverc to support different  
versions of octave.

(2) Modify savepath.m/.octaverc to remove the references to the  
version number.

(3) Remove all path information respecting octave's core functions/oct- 
files from .octaverc and load the default each time as done when  
no .octaverc exists.

Those are off the top of my head.

Anyone have thoughts as to the "big picture" pros/cons of these options?
