Thanks. Yes, this is part of the suggestion in the LaTeX Companion,  
where they mess further with \labelenumi because of the difference  
between the labels in the enumeration and the labels in the  
referencing. The only problem is that we don't know that \arabic 
{enumi} is what is the default, hence not so easy to "revert" to it.

I think I just found an easy way to do it though, by combining your  
idea with restricting the scope. I.e.
   \item One
   \item Two
   \item Three

Then the renewing of the command has no effect outside of the group,  
and \ref commands seem to print the right thing even outside of the
