M-3 M-x sort-fields

is the way to specify that it should sort on column 3.  When I do that, I
get:

>bleblebb  &  1.4.   &  10,00  &   1,00
>blahblah  &  12.2.  & 132,40  &  10,20
>blubblub  &  15.5.  &  15,40  &   2,23

Note that the sort is lexicographic, not numeric, so 8.4 will go *after*
12.2.
