/testfor doesn't work completely with scores

I don't know if this is another bug, but if you run:
/testfor @p[score_Test=score_Info]
it works, but if you use:
/testfor @p[score_Test_min=score_Info] or
/testfor @p[score_Test=score_Info_min]

You get an error message, that the provided UUID of the entity has an invalid format.
