Hi Mahesh,
There is no scope request parameter needed. It is hard to know precisely what is the issue without the trace of your call, such as provided, for example, by Fiddler. For example, here is a call that I made showing traced through Fiddler showing how this flow works. My suspicion is that you may have a typo in the grant_type parameter, which should be urn:ietf:params:oauth:grant-type:saml2-bearer with the colons escaped as below.
The HTTP request:

Content-Type: application/x-www-form-urlencoded
