Yes, they do that now and again. I used to think this could be interpreted
as top-to-bottom style with columns of length 1, but that won't explain
all the cases.

How could that be the explanation? 20$ could be changed to 120$, but
then $20 could be changed to $200.

Several countries use the style "5$79"; I suggest that is probably what
you saw.

No, the spelling's fine; the objection to the word is that it's a Latin-Greek
hybrid. (But so is "television".) There is a legend that IBM engineers
wanted to use the properly Latin form "sextidecimal", but couldn't get it
past their own marketing department.
