Order of predicate evaluation in queries at IN subclause under Where Clause

[Som]

Any one can suggest me what will be the order of execution of the values for update query under WHERE Clause IN
e.g.
update <tablename> set <columname> where <columname> IN(value1, value2, value3, value7, value5, value4)

Will oracle smart enough to sort these values inside the IN Clause in natural order
