The time I wrote this script (a while ago) I was crying for Perl with
his "cmp" and shuttle <=> Get's really "if'y" in JavaScript w/o them
:-)

function alfanum(a,b) {
 var result = 0;
 if ((typeof(a)=='number')&&(typeof(b)=='number')) {
  result = a-b;
 }
 else if ((typeof(a)=='string')&&(typeof(b)=='string')) {
  if (a < b) {result = -1;}
  else if (a > b) {result = 1;}
  else {result = 0;}
 }
 else if (typeof(a)=='string'){
  result = 1;
 }
 else {
  result = -1
 }
 return result;
}

var arr = [9,'A',8,'B',7,'C',6,'D',5,'E',4,'F',3,'G',2,'H',1];

alert(arr.sort(alfanum));
