Rake tasks are weird in 3.0.3 (db:migrate/setup)

Hello there,

Ruby 1.9.2
Rails 3.0.3
Sqlite3

I got a model like this;

class PdVersion < ActiveRecord::Base

  belongs_to :transportation
  has_many :cenarios
  has_many :users

  scope :least_users, find_by_sql("SELECT \"pd_versions\".* FROM \"pd_versions\" WHERE (outlying = 't' AND line_qty = 1 AND users_count = (SELECT MIN(users_count) from \"pd_versions\") )").first
  
end

when I run db:migrate it tells me that the pd_versions table was not found. So I assume for some weird reason, db:migrate is trying to run my scope there, which is a lot of weirdness.

Another thing is, db:setup, which was supposed to be db:migrate + db:seed right? Well when you run it, db:setup doesn't recreate the schema.rb, it keeps the same file so the migration (if you changed a migration, I know its a bad practice) it wont reflect the latest changes.
