SetTransform acting up

I am moving a couple of objects around, and while they are moved to almost the right position, they are slightly off. I have a set of objects (picture and frame/background) that I'm moving into place, but it doesn't get the rotation quite right. Anyone have an idea as to why that was happening? Here's my code:

In my mission file:
new StaticShape(TestBG) {
position = "423.425 327.807 256.847";
rotation = "0 0 -1 63.81";
scale = "1 0.1 1";
dataBlock = "BlackBox";
};
new StaticShape(TestPic) {
position = "424.079 327.224 256.847";
rotation = "0 0 -1 63.81";
scale = "0.5 0.1 0.5";
dataBlock = "PBox1";
};

My setTransform code:
TestBG.setTransform("423.425 327.807 226.847 0 0 -1 63.81");
TestPic.setTransform("423.425 327.45 226.847 0 0 -1 63.81");

Resulting placement:
placement coordinates are on, but the rotation % is off by the same amount for both, almost 8%:
