How to sort a list-like text in a cell?

Suppose I have in a cell the following unsorted list-like text:

- VAL03- VAL04- VAL01- VAL05- VAL10- VAL07- VAL08- VAL06- VAL02- VAL09

I would like to sort that list-like text. That is, in another cell I would like to get this:

- VAL01- VAL02- VAL03- VAL04- VAL05- VAL06- VAL07- VAL08- VAL09- VAL10

How can I make that?

Note: I know the SORT function but it seems to be useless for such a case.
