I'm not an MTT developer, but I'll answer #1...

MTT only looks at the return codes from the test programs that are ran. This
is all well and good, but the problem is that some Intel tests return a
meaningful value, and some don't. A while ago I went through and fixed all
the c tests so that they return a meaningful value. But I don't know Fortran,
so I did not even look at the Fortran versions of the tests. It appears that
they are not returning a meaningful value, and that somebody needs to fix
them.
