There seems to be a bit of a terminology gap here. Class['a'] does not
"have" a service.pp in any useful sense of the term. I suppose you
probably mean that *module* 'a' has a class or defined type "a::service"
whose definition resides in modules/a/manifests/service.pp. The
distinction matters, as does, in particular, whether a::service is a class
or a defined type. (In a typical module architecture, such a thing would
be a class.)
Moreover, it's unclear what you mean when you say you "use the anchor
method on the Service Type [...]." I can probably guess roughly what you
mean, but here, too, the details matter. We can give better answers if you
present code that actually exhibits the problem -- preferrably *minimal*
code that does so.

My best guess at this point is that you have a class containment issue
<https://docs.puppetlabs.com/puppet/latest/reference/lang_containment.html#containing-classes>.
That is, Puppet is very likely applying the ordering you specify, but that
doesn't have the *effect* you expect because Class['a'] and/or Class['b']
declares other classes that you consider as belonging to 'a' / 'b', but
which are not properly contained by 'a' / 'b'.
