Using a script licensed under GPL in an application licensed under a license that's not compatible with GPL

[observatory]

Hello,

My application consists of a collection of scripts (full source
distributed) licensed under a license that I'll call A.
I want to distribute with my application, the source version of a
script licensed under GPL. This script (source) will be imported and
used at runtime by my application.

Is this allowed when license A is not compatible with GPL ?

Thanks,
Andrei
