If you introspect the result from my server, you see something like this:
Notice that the first two results were numbers, not strings. I tried to 'fool' JSON a bit. I added "" to the number to see if that would do it and it didn't work. Interestingly enough, if you add " " to your data, serializeJSON will keep the padding on the strings, but removes it from the numbers. So even though my data was "10(space)", serializeJSON ignored it.
So it looks like 2 possible bugs. The client side code should allow for any simple value in the array - numbers, strings, or dates. And it looks like maybe serializeJSON is a bit overzealous in converting values. I can understand converting 10 to 10.0, but "10(space)" should be left alone, especially if "Ray(space)" is left alone.
