You could base the program on a loop. The RCX has a built in timer -
and you can read this in NQC -
http://www.informatik.uni-kiel.de/inf/von-Hanxleden/mindstorms/Programmierung/NQC/timers.html.
The loop checks the state of the sensors, and how long they have been
pressed. if the sensor is no longer active - go to a "loser" routine,
and if the time has expired do the victory routine, otherwise, stay in
the loop and continue checking and making random movements.
You may want to have another timer in the loop set up to do the random
movement - since you dont want to move every time round (it may still
be moving) - this also minimises the chance of the loop ignoring a
"hit" or "miss" because it is in other gubbins of the loop and not
checking the sensor.
I hope this helps
