Oops, you are right.  I thought that Script.prototype.exec (what s() 
calls, above) would get the activation object and cause the variable to 
be added to it, but no such luck.

Script is a bad idea, given eval (which must be treated as a special 
form, a reserved identifier).  Don't count on it being in future 
versions of any Mozilla engines.
