I believe that -groups- from SSC will help
here.
-groups- was also discussed in
Problems with tables, Part II.
Stata Journal 3(4): 420--439 (2003)
Alternatively, it's not as difficult
as you fear. -egen, group() label- or -egen,
concat()- can create cross-combinations,
after which -tab, sort- will sort in
order of frequency.
