This is not a valid version spec in nix. We would need something like 2.7.1cvs5 for nix and something else for the revision field. You could use to variables to build the version numbers for both.

Where can the rules for the name and version of packages be found?

I think I was wrong in this case:
$ nix-repl
nix-repl> :l <nixpkgs>
nix-repl> lib.getVersion "ocamlfuse-2.7.1_cvs5"
"2.7.1_cvs5"
nix-repl> lib.getVersion "ocamlfuse-2.7.1cvs5"
"2.7.1cvs5"
nix-repl> builtins.compareVersions "ocamlfuse-2.7.1cvs5" "ocamlfuse-2.7.2"
-1
nix-repl> builtins.compareVersions "ocamlfuse-2.7.1_cvs5" "ocamlfuse-2.7.2"
-1both works.

Upstream considers the version is 2.7.1-cvs5, with a dash instead of an underscore. The underscore appears only in the git tag v2.7.1_cvs5:
$ nix-build --check --option build-use-chroot true -K -A ocamlPackages.ocamlfuse 2>&1 | tee /var/tmp/nix-build.log
checking path(s) ‘/nix/store/yjwd3f799l20sl76zcqsrybjp5kgrfp4-ocamlfuse-2.7.1cvs5’

The same happens in the OPAM package.
Is 2.7.1-cvs5 a valid version in NixOS? I think so.
$ nix-repl

Maybe we should have 2.7.1-cvs5 too.

According to the manual it is:
<varlistentry><term><function>builtins.parseDrvName</function>
<replaceable>s</replaceable></term>
<listitem><para>Split the string <replaceable>s</replaceable> into
a package name and version. The package name is everything up to
but not including the first dash followed by a digit, and the
version is everything following that dash. The result is returned
in a set <literal>{ name, version }</literal>. Thus,
<literal>builtins.parseDrvName "nix-0.12pre12876"</literal>
returns <literal>{ name = "nix"; version = "0.12pre12876";
}</literal>.</para></listitem>
</varlistentry>There was a problem hiding this comment.
So the only limitation is no dashes in the name itself.

More precisely, the limitation is no dash followed by a digit in the name itself. For instance:
$ nix-repl
Welcome to Nix version 1.11.15. Type :? for help.
nix-repl> :l <nixpkgs>
Added 7837 variables.
nix-repl> builtins.parseDrvName "ocamlfuse-2.7.1-cvs5"
{ name = "ocamlfuse"; version = "2.7.1-cvs5"; }
nix-repl> builtins.parseDrvName "my-package-v2.7.1-cvs5-1.0-p3"
{ name = "my-package-v2.7.1-cvs5"; version = "1.0-p3"; }
