be sorted by row in ascending/descending order?

Given this matrix:

 57 91 31 61 16
 84  3 99 85 47
 21  6 57 91 31
 61 16 84  3 99


I want to end with this:

 21  6 57 91 31
 57 91 31 61 16
 61 16 84  3 99
 84  3 99 85 47


The 'order' of the sort is: 3 1 4 2

Also, what R expression will give me the 'order'?

Thanks.
