I have not much experience with Nuxeo, but here is for Alfresco:

1.If possible DMS should be open source

Yes.

2.Initially DMS should support up to 500 users

Yes, if you have a good server.

3.System should be scalable in sence od users or content

Yes.

4.Docuemtns/Content should be stored on a file system

Yes. Only metadata is stored in a database.

5.Document should be able to be marked for later destruction

The free Records Management module has retention capabilities.

6.Mandatory to have workflow capabilities

Yes.

7.Mandatory to have version control capability

Yes.

8.Nice to have SSO(Single Sign On) with Liferay portal

Yes.

9.Nice to have posibility to expose some of funccionality via portlets in Liferay

Alfresco and Liferay work very well together.

10.Document management should be done via the web interface

Yes.

11.Nice to have shared drive capability

Yes.

12.Nice to have events and notifications about add/change content

Not sure about this one. The Share module has this feature, but not sure about the main DM application.

Don't know the Nuxeo system, but we are using Alfresco as a document storage and session server. We have our own GUI and only use it as a back-end system. So far we had no problems. Plus Alfresco has a nice REST interface which makes it easy to integrate into any existing system.
