You direct stdout (output of echo) and stderr (output of --bar) both to
the terminal, which is why things get distorted.

Try redirecting outputs somewhere else:
$ parallel --tagstring {%} --bar echo {} ::: a b c d e  2>tmp
3   c
4       d
2       b
1       a
5       e
$ cat -v tmp
^M^M#   0 sec d
                                          ^M0^M^[[7m^[[0m0% 0:5=0s d

...etc.

Don't know if this fixes your --tagstring issue, too.
