You can through the ControlPort with:

  "GETINFO sr/current"
  "GETINFO sr/previous"

From control-spec.txt:

    "sr/current"                                                           
    "sr/previous"                                                        
      The current or previous shared random value, as received in the    
      consensus, base-64 encoded.  An empty value means that either   
      the consensus has no shared random value, or Tor has no consensus. 

Cheers!
David
