I'd plant them so that the bulbs don't dry rot on you. This way they will grow, replenish the bulbs and be ready for next year. You do have a shot that they will bloom before a frost.
I agree, there is no place for a bulb out of the ground, I would let them spend whatever time left to the season in just producing some leaf to pull in the sun's rays and draw nutrients in for next year's big blooming.
If Glads cannot be left in the ground where you are then just treat them as you normally would at the end of the season; mulching or cold boxing them in the garage sort of thing.
I bet you will be Glad you planted your Glads! Yuk Yuk LOL
I think I will plant them now and keep them from flowering. At our last house I dug them up in September, so I think I will do the same. They won't have a full season, but maybe it will be better than not doing anything until May when I can plant them again. I got 50 corms for $5, so if half of them make it, I'll still feel pretty good.
