Mathematically it actually does. If you want to divide a total into equal whole parts (so without using decimals) the number 10 actually isn't that good, since you can divide only by 10, 5 and 2. 12 on the other hand has five: 12, 6, 4, 3 and 2. The higher the multiples of 12 get, the more divisions fit in. With multiples of ten it actually doesn't get that much better.

So 12, 24, 48, 120, and 240 are way better totals for simple divisions for - let's say - packs of goods, time or money to be divided into equal parts that cannot or are easier not to be subdivided.
