Mathematically, 10 is a pretty arbitrary choice to base your number system on. We would have been better off learning base 12 than inventing metric.
In fact some googling reveals than the choice is not arbitrary: http://math.stackexchange.com/questions/8734/why-have-we-cho...
BTW: this discussion is quite off-topic. The choice for the number system base is quite different from the choice for the number of columns for a CSS grid.
When the code base is small enough, choosing the library doesn't mean half-blindly trusting it to do what it's supposed to do (up to 4k lines it's still easy to quickly review the content of the library and check if an issue would be easily fixable) and you can always exchange it for another component, or just write your one if really it doesn't fit your use.
And from another point of view, it should be a good learning tool to see how things are done if you're not familiar yet with the problem it solves.
edit: clarity
It would be nice if your browser support was a little more informative than "The latest versions of Chrome, FF, Safari". What platforms are you supporting? FF runs on multiple devices nowadays and although it has the same rendering engine there are subtle differences (particularly in font rendering). Also you should set a baseline for browsers, as my users don't use the latest versions of a browser, and we have a minimum requirement.
As said already it's a little odd to go with a 10 column grid, given that 12 is more divisible.
On a more general note, wouldn't it be nice if front-end CSS frameworks were more inter-operable. Let's say I want to use Foundation's forms, Simple Grid's grid and Bootstrap's alert I would have to compile Bootstrap and Foundation separately and then learn the proprietary markup and classes that Foundation uses for its forms, and then do the same for Simple Grid's grid and Bootstrap's alerts. In an ideal world the markup would be consistent and the classes and you could simply switch out your CSS files to try different things.
I'm not sure what will fit in a the one, two, and three width columns... possibly an image. But the wrapping text in each column for the 420px container is going to look a bit off.
b) It isn't "even less than 2 kb"

Another thing that would be cool is a generic css layout framework..basically a more robust form of the grid...something like this http://layout.jquery-dev.net/ but perhaps have only jquery as dependency and styling being up to user.
