I wouldn't worry about it.

The most likely explanation is that a search crawler / indexer has cached the old URLs and is checking them again to make sure they're still valid. Since ScriptResource.axd returns 404 for these now-incorrect URLs, the search crawler will eventually flush them from its cache, and over time you'll see these errors disappear.
