There is no contextInitialized() method defined on Servlet, only on ServletContextListener.
The order in which servlets are initialized can be configured via the servlet's load-on-startup element.
However, given that you mention the contextInitialized() method, I assume you're really interested in the order in which ServletContextListeners are invoked? Unfortunately, the current Servlet spec does not provide any mechanism for specifying this order.
