Overall exposure is 1 stop lower for the t-bird shot (f/22->f/11 = +2 stops, 1/60->1/500 = -3 stops, so total 1 stop less). You'd expect with the C-PL that you'd need something like an extra 1.5-2.0 stops to overcome the loss of light, so your exposure in total is going to be off something like 2.5-3.0 full stops on the t-bird shot.
There's plenty to recommend about your settings. In general I'd recommend shooting at base ISO in bright sunlight, and opening up the aperture considerably (f/8 is plenty for this kind of shot, or even larger if you want greater subject isolation), and in general to keep an eye on the histogram to be sure exposure is ok especially with a white subject which is notoriously difficult to expose correctly.
As far as the matrix meter's performance, it looks it failed here, but I'm afraid your AF settings (AF-A/dynamic 3D) throw a wrench into the works. We do know that (right or wrong) the matrix meter will vary exposure based on what's under the active AF bracket. You might get better consistency if you take control over the AF system (it's questionable why you'd use these settings for a stationary object). I don't believe this should be able to explain away a 3-stop fail but when you're dealing with areas of bright white close to dark tones, any metering mode can be thrown off.
