Possible error in version 3.1 ???

Hi
First post.
Just updated to 3.1 (Build 990)
And a rule that has been working for almost 2 years now, doesn't seem to work anymore.
- Start a application, followed by a embedded script "sleep 60", followed by move to trash.
I think that the sleep script is not working anymore.
Is this maybe a bug, or has something changed?
Thanks in advance for your time.
