When adding/remove peers/nodes we track the scores so we can quickly query the state for quorum
detection.

Mostly good, additions/subtractions/asserts are done in the right place.
The main problem is the name of the variables being confusing. The tests can be improved a bit (see suggestions).

You don't register or allocate a score, do you ?

Don't rely on peer id, retrieve it instead

You never checked that the scores sum up in the presence of several peers

uint32_t score1 = 10000000 * MIN_VALID_PROOF_SCORE;
auto proof = buildRandomProof(score1);

Dito

You can also test that removing a peer with nodes reduce the allocated score as expected

Let's try to align with the getavalancheinfo rpc as much as possible, since the names have already been discussed there totalPeersScore.

I don't see the point of splitting this, there is no reason not to use the actual facility directly.
You can still check the registration is successful with BOOST_CHECK_NE(TestPeerManager::registerAndGetPeerId(pm, proof), NO_PEER);

The peerid changes when the peer is moved out of and back into the valid pool, so getting the peerid when it's first registered doesn't help.

Update variable and method names.
