I guess I would ask what indications you have that she is ready to start K this year. If she seems solidly ahead on K skills, I think I'd assume that the test was inaccurate and try the WJ. If she doesn't seem to be pretty far ahead, I might not bother testing again until she's older (and the tests are likely to be more accurate). Her WPPSI scores look to be in the moderately gifted range (~98%), and she may do fine in a regular classroom if she's not too far ahead of her peers in terms of achievement.
As far as a LD is concerned, I wouldn't worry about it at this point if you don't have another reason to think that it could be an issue. Testing at 4 is really pretty sketchy.
