No, I don't think it does. OpenSSO is originally designed to have a 
single administrator for managing policies and not for different users 
creating their individual policy (although this is in the pipeline of 
development at the moment). Therefore, the aspect of controlling the 
number of policies has been neglected.
Other aspects of accounting (e.g. failed attempts to authenticate) are 
explicitly covered by a special logging service, but I don't think quota is.
