We solve this issue by doing (kind of ugly) stuff like this in our modules:
unless => 'if ( ! ( Get-Service mcollectived ) ) { exit 1 }',
If you don't like that syntax, you may be able to use the $? or
$LastExitCode variables that get set by PowerShell (I haven't tested
this, however). Both of those have non-obvious gotchas. A good writeup
on error handling in PS (not Puppet-specific) is here:

Hi Guys,
So I've been working with puppet on windows and I think my approach is
all wrong. I've been using the puppetlabs/powershell module to run
commands, however I'm having difficulty with exit codes. Primarily
puppet expects exit codes to denote success/failure, whereas
powershell is returning objects (and giving a 0 exit code regardless
of result).
I'm automating the install of old bits of software, so getting
meaningful answers out of the installers is pretty difficult, this
means that the scripts are a bit ugly and not very idempotent.
Typically I have to check a log file to find out if the install
actually worked.
Are there any examples out there of windows puppet automation that
makes heavy use of the powershell module?
Cheers,
Tom
