In those cases the court found the intent manifest in the language. These were sophisticated parties with legal advice. Even if they court didn't see intent, it is within the courts' power to force such persons to follow the language if for nothing else than to serve as example to other negligent contract drafters.

A court will only grant that which is asked for. So for a typo to matter, one of the two parties before the court must be claiming that is isn't a typo.

There are also cases of people selling cars (and other stuff) ultra cheap on ebay, because they misplaced a comma when specifying a price.

Prices for the sale of consumer goods are subject to some special rules, mostly to prevent bait-and-switch advertising. But actual typos happen all the time and are corrected. There are a great many instances of airline websites getting prices horribly wrong. These contracts are not normally honoured and wouldn't be enforced by a court (40,000$ tickets for 50$ sort of things). Much depends on the specific facts and whether the price is obviously a mistake.
