Strange sorting results in javascripts
The SORT function in javascripts cannot return the correct answer in some situations.
I am using http://jsconsole.com to check some examples:
[2, 10].sort()[2, 10]
[3, 10].sort()[10, 3]
[9, 10].sort()[10, 9]
[10, 11].sort()[10, 11]
I tested it on windows xp, windows 2008 with firefox and chrome.

I think you are confusing Java with JavaScript, but they are completely different programming languages. I'm pretty sure the code is JavaScript.
Default sort function for JavaScript sorting by string value rather than integer value. You have to do the latter manually, but it's pretty simple:
[3,10].sort(function (a, b) { return a - b; });
