Sorting a string array numerically - How do I do it?

Hi,

Supposing I have an array with the following in:

 
myArray = ['left_1', 'left_3', '_left_5', '_left_12', 'left_10', 'left_2', 'left_6', 'left_9'];

If I want to sort that array numerically and I use myArray.sort(); or myArray.sort(Array.NUMERIC); left_10 always comes before left_1.

Because each item in my array has numbers and letters I think this is causing the problem. So my question is: does anyone know of a way of doing this?

Would I need a custom function and call it like this?

myArray.sort(customFunction);

Basically I want to sort the array so that the 1_left comes before 10_left and so on…

Any help is appreciated.

Thanks!!
