There is a fairly systematic discussion in 

SJ-9-1  pr0046  . . . . . . . . . . . . . . . . . . .  Speaking Stata: Rowwise
        (help rowsort, rowranks if installed) . . . . . . . . . . .  N. J. Cox
        Q1/09   SJ 9(1):137--157
        shows how to exploit functions, egen functions, and Mata
        for working rowwise; rowsort and rowranks are introduced

There is (now) not much difference in effect between my -rowsort- and Jeff Arnold's -sortrows-; note that there is also -rowranks- as well.

You could use Jeffrey Arnold's -sortrows- (use -findit- to locate download).

input col1 col2 col3 col4 col5
101 101 . . .
. 111 333 . .
. . . . 935
. . . 23 16
405 .295 . .
end
l
sortrows, replace
