You might get more responses if your change your title. Your title Understanding rpart package is too vague. A better title would be something like Why does rpart generate a different tree when the order of the variables in the data is changed?.

You did not provide a reproducible example, there is no ptitanic data in base R, nor in rpart package. As about the results, they are nearly the same -- the only difference is that pruning returned one extra level.
