Tom will know it.
If you say "Tom must know it" that can display a bit of uncertainty depending on how it is said. With written word you cannot be certain where the reader will put emphasis in the sentence.
Tom should know it.
"Tom may know it" displays uncertainty to a greater degree. "Should" implies a greater degree of certainty.
