Personally, I would be disinclined to see dyslexia in those scores. I highly recommend trying either large print books, a line guide short enough to sweep across the page, or a small colored overlay before looking at more complex interventions. I really have seen a pattern with kids who take in the "whole word" or "whole sentence" at once being less fluent and more "tired out" by reading. I see it less as a disability question than as an environmental comfort question--sort of like how some people can't relax in a cluttered environment or an environment with background noise. Page clutter can be unpleasant too.
Someone once posed a great question to me about senses: which sense did I recieve the most pleasure/comfort through and which sense did I recieve the most discomfort/irritation through. One night when I was a camp counselor I posed the question to a group of other counselors while we were staffing an overnight. It was fascinating. I don't think I really appreciated until that night how differently people could be impacted by the same stimuli. It's definitely broadened my thinking about what may and may not constitute an overwhelming distraction or irritant to someone else.
