Is squid 2.7 Content-Range aware? Since these requests work in 2.7, is 2.7 just ignoring the range requests?

Which quite likely triggers confusion within Squid as the store/object
interface is range aware. Has been issues there in the past, and quite
likely is more issues..

Not 100% sure that response is technically broken, but it surely is an
odd response.

Why isn't it?

We don't know how the server would react on requests for the same URI
but with Range header..

There is no Content-Location header in the response, so merging of
responses with different url parameters MUST NOT be done by any HTTP
agent (including proxies). Content-aware merging of the data is allowed,
but that's outside HTTP.
