Abel,
It sounds like you're checking for TXT records of the form
_domainkey.{domain}.tw . I suspect strongly that the "misconfigured"
domains that you are seeing are the result of wildcard SPF records: a
domain that publishes an SPF record for *.example.tw would normally also
have that record appear as _domainkey.example.tw , unless there were
other _domainkey.example.tw records of any type.
It might be interesting to repeat the query for a very unlikely name,
such as alskdj9qhnscdfjfoi3.{domain}.tw, and see if you get the same 715
domains.
Of course, these records are policy records for DomainKeys, not DKIM.

As I tested the all the domains of ccTLD .tw ,included IDN:
553 domains own correct domainkey relative resource records of total 180142
domains
And
715 domains mis-configure them to "v=spf1 ..."

FYI. [1]
Contact Lars with comments if you've got any.
I believe that his current approach doesn't distinguish
4871 from 4870 domains. If someone could help him do
that, that'd be good IMO.
Cheers,
Stephen.
