Does Orange scale the data automatically for the linear regression with Ridge regularization
Not by default, no, as shown by the normalise=False here:


  class Orange.regression.linear.RidgeRegressionLearner(alpha=1.0,
  fit_intercept=True, normalize=False, copy_X=True, max_iter=None,
  tol=0.001, solver='auto', preprocessors=None)
