If I hunt in a open general rifle hunt in Oct and I am not successful and the same unit has an open general archery hunt in Nov can I hunt archery in Nov with the same tag??

Yes.  The general season tag can be used in an any-weapon hunt and, with the addition of an archery validation, used in an archery-only hunt.  Here is the information you asked for for unit 39:   General Season-Any Weapon Regular Tag 10/10/13-10/31/13 Antlered Mule and White-tailed Deer Any Weapon Unit 39 10/10/13-10/31/13 Antlerless Mule and White-tailed Deer Any Weapon Unit 39¹ White-tailed Deer Tag 10/10/13-10/31/13 Either-sex White-tailed Deer Any Weapon Unit 39*         General Season-Archery Regular Tag 11/10/13-11/30/13 Either-sex Mule and White-tailed Deer Archery Unit 39* White-tailed Deer Tag Unlimited permits 11/10/13-11/30/13 Either-sex White-tailed Deer Archery Unit 39*
