I don't believe there's a one-step way, but here's what I would do. I
assume your numbers are in A1:A100; make appropriate adjustments for
their actual location.

1. In C1, type  =RAND()
2. Click and drag C1:C100 to fill the cells with the formulas.
3. Highlight C1:C100, Edit | Copy.
4. Highlight B1:B100, Edit | Paste Special and select Values.
(This ensures that the random numbers won't change during the sort.
It might be an unnecessary precaution, but does no harm.)
5. Highlight A1:B100, Data | Sort, sort Ascending on Column B. Make
sure "No header row" is selected.
6. Delete columns B and C.

If you just wanted 100 random integers, that's easy enough with
    =1+int(100*rand())
But it looks like you want to ensure all 100 integers are in the
list, with no duplicates. That's what makes the extra work.
