sub nn{my$x=pop;(sort{$b<=>$a}map{abs($_-$x)}@_)[0,1]}

I guess that is 46 chars.

Update: Sorry (oops), make that:

sub nn{my$x=pop; (map$_->[0],sort{$a->[1]<=>$b->[1]}map[$_,abs$_-$x],@_)[0,1]} # or sub nn2{my$x=pop; my@d=map abs$_-$x,@_;@_[(sort{$d[$a]<=>$d[$b]}0..$#_)[0,1]]}
for 69 or 68 chars.

Update: Well, those last two are okay solutions for the wrong problem. *sigh* (:
