Typically, it's difficult to see the difference between sensor sizes simply by going over specs. The pic below should give you a stronger sense of the sensor measurements in the TG-310 and WG-3.
All in all, the two cameras posses the exact same sensor measurements but not the same resolution. You should expect to see the Pentax WG-3 to offer you greater detail with its extra 2 Megapixels. Greater resolution will help you crop pics somewhat more aggressively. The more aged TG-310 is going to be disadvantaged when it comes to sensor tech.
