Tree lily bulbs - boxed for a month. What to do?

Hi everyone,

I'm a very unexperienced gardener on this cold land and bulbs are totally new to me.
Ordered some tree lilies bulbs during Autumn but the delivery took ages.
They finally arrived mid January but the weather here in Scotland made impossible to do anything so far outside. I've kept the box closed (yes, I've recently realized it was not the best idea...) outside on the cold weather and protected from rain, frost and snow.
My question: is it still worthy to plant them? And, if so, for how much longer can I wait? (weather forecast here still pretty grim)
Thank you very much for your attention.
Cheers from chilly Scotland
