bq. How does changing the schema version cause any of those?

It can't and it doesn't. Those should be separate JIRA tickets, if valid at all.

This patch is only addressing the difference in digest calculation, which is objectively an issue and has been reproduced.

> As the order of SchemaKeyspace is changed ([6991556 | https://github.com/apache/cassandra/commit/6991556e431a51575744248a4c484270c4f918c9], CASSANDRA-12213), the result of function [{{calculateSchemaDigest}}|https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/schema/SchemaKeyspace.java#L311] is also changed for the same schema. Which causes schema mismatch while upgrading 3.0.x -> 3.0.13.
