It seems that myDoc.characterStyles is a regular object with a length 
property added to it, not an actual array.

Another major difference between the for/in and traditional loops is 
that the for/in loop will not loop through the full length of the array 
if it has undefined items whereas the traditional for loop will.

For example:

myDoc = app.activeDocument;
myArray = new Array(myDoc.characterStyles.length)
myArray[3] = 4;
for (j in myArray)
$.writeln(j)

Will only loop once despite the fact that there may be more than one 
character style in the document.
