Ok, the above answer can be made more impartial using the following 
critiria,
(a) does the "purpose" of a function suggest a certain solution
(b) which solution is more powerful,  i.e. which  solution  can be used 
in a wider range of  applications
(c) efficiency of the implementation, which  solution provides a higher 
performance ?
(d) ... <something I forgot> ?

With respect to the question whether NaNs should be sorted to which end, 
criteria (a) and (b) do not suggest any preferred solution. Therefore, 
only criteria (c) should be applied.
