Frames btw scenes?

Hi everyone!
I am here trying to do something quite simple but::spin:

I am in the scene A and i switch to scene B, but the current frame in B doesn’t get syncronized with the current frame in A.

Has Blender a secret way to maintain the same frame position in the time line betwhen scenes?

Thanks vey much in advance!

I was helped in BlenderArtist Python forum by the great user Loolarge.
I must to use a script provided by him.
