Castle Windsor IOC and order of appearance in the config file

I'm new to Castle Windsor and confused about ordering in the config file. This is taken from the GettingStarted1 example. The HttpServiceWatcher class uses the IFailureNotifier constructor in it. However, no matter how I order two components that implement this interface - AlarmFailureNotifier and EmailFailureNotifier - I always get EmailFailureNotifier. I know that you can override which one is selected using parameters and a link to "service lookup", but I thought the order of declaration is used when other mechanisms are not.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="castle"
             type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler,Castle.Windsor" />
  </configSections>

  <castle>
    <components>

      <component
        id="httpservicewatcher"
        type="GettingStartedPart1.HttpServiceWatcher, GettingStartedPart1">
      </component>

      <component
        id="alarm.notifier"
        service="GettingStartedPart1.IFailureNotifier, GettingStartedPart1"
        type="GettingStartedPart1.AlarmFailureNotifier, GettingStartedPart1" />

      <component
        id="email.notifier"
        service="GettingStartedPart1.IFailureNotifier, GettingStartedPart1"
        type="GettingStartedPart1.EmailFailureNotifier, GettingStartedPart1" />

      <component
        id="form.component"
        type="GettingStartedPart1.Form1,GettingStartedPart1" />

    </components>

  </castle>
</configuration>
