SQL 2008R2 - Performance Condition alert for CPU Threshold event

Question

I am trying to use SQLServer Agent alert for Resoure governor setup. I would like to be alerted when CPU threshold -> REQUEST_MAX_CPU_TIME_SEC >  20 -> is crossed for any particular query. I am in RTM version for SQL2008R2. For some reason
the alert never occurs thru SQL Agent Alert.
Here is my alert configuration
EXEC msdb.dbo.sp_add_alert
@name=N'CPU Alert',
@message_id = 0,
@severity = 0,
@enabled = 1,
@delay_between_responses = 60,
@include_event_description_in = 1,
@notification_message = N'Email from alert CPU',
@category_name = N'[Uncategorized]',
@performance_condition = N'MSSQL$XXXXXX:Workload Group Stats|Max request cpu time (ms)|default|>|1',
@job_id = N'00000000-0000-0000-0000-000000000000'
THe same alert is working if I put < 5, I am able to notified by email. But when I put > I dont see any alert.
I have tried changing the default setting for resource governor to various #s (1, 5, 20, 600) . But for any change, if i use perf condition > 5, i dont get any alert. If i use < 5 then i get alerts...
Is it a bug, or am i missing something...
Any help will be much appreciated...

I got the event notifications / service broker solution working.  Thanks to
Aaron Bertrand blog for providing me with a working model.
I ended up using Aaron's code to create a more generic framework to support the processing of any number of trace events (not just exceeding resource governor's max cpu). 
Here it is... use at your own risk:
-- Create the Target Service:
USE msdb;
go
CREATE QUEUE eventNotificationsQueue ;

CREATE SERVICE eventNotificationsService
ON QUEUE eventNotificationsQueue ( [http://schemas.microsoft.com/SQL/Notifications/PostEventNotification] );

CREATE ROUTE eventNotificationsRoute
WITH SERVICE_NAME = 'eventNotificationsService',
ADDRESS = 'LOCAL';
GO
-- Create the event notification:
-- SQL Trace Event Types: http://msdn.microsoft.com/en-us/library/ms186265.aspx
-- drop event NOTIFICATION [CPUThresholdExceededNotification] on server
CREATE EVENT NOTIFICATION CPU_THRESHOLD_EXCEEDEDNotification
    ON SERVER 
WITH FAN_IN
    FOR CPU_THRESHOLD_EXCEEDED
    TO SERVICE 'eventNotificationsService', 'current database';
GO
