you know there is a typo, right? "CreateTier3DiscountountGroups" (on database your table is named "tier_3_discountount_groups " or "tier_3_discount_groups"?). Also, you can use "column_exists?", like this:
--
-- add_column :tier_3_discount_groups, :description, :text unless column_exists? :tier_3_discount_groups, :description--
