The values returned by tune() are Mean Squared Errors in case of regression, and simple rates (*no* percentages) in case of classification. As Andy already suggested, you might want to check if your target variable is indeed a factor. In case it is and you still get values greater than 1, drop me a mail with a piece of code (and data) enabling me to reproduce the phenomenon.
