Imo, the reason Percy seemed weaker in HoO was because the first series made him over-powered. By the time we got to HoO, Percy's power had to be dialled down so that he wouldn't overshadow the rest of the Seven, and so that Gaea and the giants actually seem like a threat. Also, it should be noted that the change from 1st person narrative to 3rd person could also account for the sudden shift in Percy's strength.
