The fight clearly entails a neutral scenario, so Captain America wouldn't use Mjolnir because it's Thor's weapon, and because of that it's not at his immediate disposal at any given moment.

And like I mentioned five years ago, most of Captain America's means for disabling Iron Man's armor require direct contact with Tony, not to mention such items are not part of his regular repertoire. Iron Man has an advantage in ranged combat that Captain America lacks, not to mention he possesses defenses like force field shields. Iron Man could just fly 30 feet upwards and rain fire on Captain America. Of course I think Captain America can't win. The odds are 50-1 against him, and I think I'm being generous.
