Incorrect! Proof: 

$ perl -e '@names = (["Nan Tregar"], ["Sam Tregar"]); @names = sort { 
+$a->[0] <=> $b->[0] } @names;'
Sort subroutine didn't return a numeric value at -e line 1.

Note that you have to work a little. Just a straight { $a <=> $b } gets optimized into something that doesn't do the NaN conversion.
