It is only a problem with ^^ notation. Your solution works "in  TeX's
stomach" but in order to make ^^ work properly, two adjacent
characters with category 7 must be seen "in TeX's mouth". I am afraid
that ^ is activated in several languages. If such a language package
is loaded and the language is not currently active, then ^ expands to
^ with character 7 so that it works properly in math but it is to late
for ^^. Other puctuation characters can be used in \label, \ref,
\cline, \hline, \hhline and here your solution will work (I hope).
