Here is my jsFiddle code.

Please help me out of this. I want sort it in ascending order according to the class names product_tag-pro-1, product_tag-pro-2 ... etc.. But the lists are arranging according to the post-* numbers.

I could not find out the solution. 

for(var i=1; i<=jQuery("body.term-california-online-practice-exams ul.products li").length; i++){
    var s = productContainer.find(">li:nth-child("+i+")").attr('class').split(' ').join('.');

    productContainer.append(productContainer.find("li").get().sort(function(a, b) {
        return parseInt(jQuery(a).attr("class").match(/\d+/), 10) - parseInt(jQuery(b).attr("class").match(/\d+/), 10)
    }))


}

The problem is your regex /\d+/ which selects the first instance of digits in your classname, instead you need to target digits that follows product_tag-pro-.

You can also simplify the sorting logic like

var productContainer = jQuery("ul.products");

productContainer.children().sort(function(a, b) {
  return a.className.match(/product_tag-pro-(\d+)/)[1] - b.className.match(/product_tag-pro-(\d+)/)[1]
}).appendTo(productContainer)

Try jQuery's own native sort method, for numbers you can use 

numbers.sort(function(a, b){return a-b});


var productContainer = $('.product-wrap').find('ul.products'); // get the container for the lines
var lines = productContainer.find('li'); // get all the lines
var numbers = []; // set up an empty number array
lines.each(function(){
  // split off the number between 'product_tag-pro-' and the following space, if there is one, and add it to our empty number array
    numbers.push(parseInt($(this).attr('class').split('product_tag-pro-')[1].split(' ')[0])) 
});
var sorted = numbers.sort(function(a, b){return a-b}); // sort the numbers
$.each(sorted, function(){
    productContainer.append($('.product_tag-pro-' + this)); // sort the array in turn
});
h1, h2, h3, h4, h5, h6{ font-weight:normal; margin:0; font-size:16px;}
.product-wrap{ margin:0px auto; width:960px;}
.products{ list-style:none; border:1px solid #000; padding:0; margin:0;}
.products li{ border-bottom:1px solid #000; padding:0 10px;}
.products li:last-child{ border-bottom:0px none;}
