Still didn't work !!!
I changed to "stand 1 track s0 20", so that decrement portion is greater the
difference of priorities on both routers.
whatelse am I missing?

J,
Diagnosis:
By default when the tracked interface goes down the standy command reduces
the priority of the active router by 10 .Since R1 has been configured with a
priority of 100 and R2 with a priority of 90 the failure of the track
interface has no effect on the relative priorities, which is what you
observed.
Recommendation:
For your config to work you must either keep the standby priorities of the
r1 and r2 within 10 of each other , or change the amount by which the
priority is reduced when the tracked interface fails using the command
"standby 1 track Serial0 XX" on the router with the higher priority ,where
XX is greater than the difference between the configured priorities.
