Congratulations on a great find, lalatan!
I guess it's time to reassess what is possible, since this was unexpected.
Spike1007 refreshed me on special letters and mentioned can have one of each add to score
(1 for J & K, 2 for X, 3 for Z, and 4 for Q).
So if there some word that had at least one of each, could have up to 11 extra points on top of 2*25=50 for 25 letter ultra rare word.
That seems to indicate 61 max points limit.
If there's one higher scorer, maybe there's another that gets even closer to the limit.

For example, This word has X,Z,Q and is singular with 24 letters: 48+2+3+4=55
So its plural might still be out there to be discovered, for 57 points.

Congratulations lalatan! I had given up on those.
