Where should be correct set Javascript for Google map?

JavaScript
1

I have seen article:

As I have seen this script blocks other Javascripts with jQuery I wonder how is correct place for this?

Example:

  1. Jquery script application:jquery-1.7.2.min.js
  2. Page where is map
  3. This code on the SAME page where is map and NOT included file like
    <script type=“text/javascript” src=“/js/javascript.js”></script>

Is this correct or this script can be set inside included file?
How does it influence other scripts regarding priorities?
