There are no new dogmas, only new definitions of truths which already exists like the Assumption. There is no dogmatic declaration that the Eucharistic elements ought to be bread and wine except for the fact that Christ used them at the Last Supper and the Church has continued the practice of Christ. Christ ordained the 12 apostles at the Last Supper, the apostles chose between 2 'men' to replace Judas, ordained 7 'men' as deacons.  As LG states the apostles ordained 'men' to succeed them and this has been the Church's practice following Christ and His apostles ever since.
As I said, the author of TOB does not draw the same conclusions from it as you do, with respect I would say that St John Paul is in the best position to interpret what he, himself wrote.
Ordinatio Sacerdotalis has all the hallmarks of an infallible declaration of a truth. The Pope was solemnly declaring, 'confirming the brethren' that the Church has no authority from Christ to ordain women.
