I think because the source code is much more readable.

Okay...

But maybe we can even do it better... we just define that our "comparator" 
function will return a value less than zero if the first parameter is smaller 
than the second one, 0 if they are both equal and more than zero if the first 
parameter is greater than the second one.

olsr_32_t time_cmp(const olsr_u32_t t1, const olsr_u32_t t2)
{
   return t1 - t2;
}

We just have to remember this definition when we use the function.
