If you want to attach an event listener inside bootstrap.php file of your plugin, everything should work fine using the hints posted in the answers. Here is my code (which works properly):

MyPlugin/Config/bootstrap.php:

App::uses('CakeEventManager', 'Event');
App::uses('MyEventListener', 'MyPlugin.Lib/Event');
CakeEventManager::instance()->attach(new MyEventListener());

MyPlugin/Lib/Event/MyEventListener.php:

App::uses('CakeEventListener', 'Event');
class MyEventListener implements CakeEventListener {
    ...
}

Event listeners related to MyPlugin are being registered only when the plugin is loaded. If I don't want to use the plugin, event listeners are not attached. I think this is a clean solution when you want to add some functionality in various places in your app using a plugin.
