what difference between using a script tag and code behind in asp.net
The <script> tag in asp.net is used to define the client-side script. The <script> tag contains the scripting statements, or it points to an external script file.
Code Behind refers to the code for an ASP.NET Web page that is written in a separate class file that can have the extension of .aspx.cs or .aspx.vb depending on the language used. Here the code is compiled into a separate class from which the .aspx file
derives. You can write the code in a separate .cs or .vb code file for each .aspx page. One major point of Code Behind is that the code for all the Web pages is compiled into a DLL file that allows the web pages to be hosted free from any Inline server code.

To add to what samwu said, code behind runs on the server, not in the local browser. Javascript runs locally. You need to know the difference between what runs locally and what needs information sent back to the server to be handled.
I'm surprised that the book you are reading does not specifically state this fact. Seems a little odd... Anyway, notice the script tag has a runat="server" attribute. ASP.NET Web Forms allows you to have a separate code behind file or a single file that
combines markup and server side code.
To expand on mgbehard's response, that script section is actually C# code-behind. The runat="server" attribute means it runs on the server. You are looking at an .aspx example where the code behind is in a runat="server" script section in the .aspx page
rather than in an associated, separate .aspx.cs file. Either way works. For larger pieces of code it is easier to maintain in a separate code file.
And, repeating what I said earlier, ASP is not ASP.NET. Your example is ASP.NET.

Classic asp uses VbScript.

Classic asp powered web applcation from the late 90s to the early 2000s.

That's ASP.NET.
