unfortunately the RTEMS 10 release branch reports the same revision 
number (__RTEMS_REVISION__) as the 4.10.2 release. Do you want to use 
the branch? With a 4.10.3 release, the __RTEMS_REVISION__ would change to 3.

Independent of this, accessing internal data of the score always can 
case problems. If a certain information is important for you, then it 
would be better in the long run to add an API for this to RTEMS which is 
documented and tested.

For example, pthread_getschedparam() returns the real priority.
