-fre- is excellent for this and related problems. 

But there are other solutions too which have been around for some time.  

-modes- from SJ does what Rodrigo wants. So would -groups- from SSC. 

-groups- has one advantage over -modes- or -fre-: it extends to frequencies of two or more variables considered jointly.

One could think of constructs with the -in- qualifier here, but Maarten`s answer is unbeatable: -ssc d fre- takes care of both ordering and subsetting the values...
