Works for me in bash (4.0.35), but fails the way you say in dash (if only I could figure out the option that tells me the version!).

This works however:

  type does-not-exist.sh 2>/dev/null && . does-not-exist.sh

I suspect it only works if the script is executable, as otherwise type would not find it (but . would). But at least on my system, it is.
