(102.4 ± 7.3 to 109.5 ± 5.8, p=0.004)

106 is well within a standard deviation of both of those. In fact, 109.5 is only one standard deviation away from the first, and the reverse is almost true. How do they get p = 0.004?

The baseline score was (86.6 ± 9.2). You are seeing the improved score (maybe the 95% confidence interval?).

Yeah good point, it might be the 95% confidence interval and not the standard deviation.
