It's too hard to "guess" on what is a very safety-critical question as the condition of the tires is something that would warrant a careful inspection to render anything even close to an informed opinion.
For example, if the tandem had been stored hanging from the ceiling for 3 years in the back of the shop where it wasn't sitting exposed to UV light all day and they still feel supple, they may be just fine. However, if the tandem was left sitting with those tires under-inflated or flat for any period of time with resultant sidewall damage, or if it was sitting in the front window of the shop getting 12 hours of UV light each day, they'd be toast.
Therefore, it's really on you to decide if you know enough about those tires based on your own inspection to continue with their use. If you did decide to use them, at least on a limited basis, I'd make a point of giving them a thorough inspection after each use to see if there are any indications of casing deformation, sidewall distress, or compound cracking. At the first hint of a problem, toss them and put on something new.
If it was me, when in doubt about tires I replace them.
As for what tires to use if and when you do replace them, if you're happy with Armadillos on your regular ride, then try them on your tandem. If they feel OK, then use the same tire or perhaps a larger diameter model as warranted for your combined team weight.
