I pretty much follow a similar route and list my skills at the bottom of my resume, grouped into three categories of current experience, past experience and exposure to. In addition, I tend to add a final summary after each of my past jobs with a comma separated list of what I actually learned or utilized on the job during that time. As a hiring manager, I see a lot of resumes, and I rarely see skills being cleanly defined; so most of the time I parse the descriptions of people's past jobs and determine what they were doing, and what questions I needed to focus on to get the information I needed to make a decision. Additionally, I will use key things in a resume as a reasoning to ask certain things. If someone mentions design patterns, then I will be asking them about design patterns. If someone said they worked on a project, I will ask them what their level of involvement was, and how they worked with others. Personally I think it would be great to have a clearly delineated list of skills, grouped they way you do it. The reality is, when you look at a ton of resumes, you eventually follow your own 5-second rule. If a resume can't grab your attention within 5 seconds of skimming through it, then it's probably not worth your time (and it might seem harsh, but there's plenty you can pick-up on in that short amount of time).
