Does a Re-entry Permit guarantee that a permanent resident will be readmitted to the U.S. ?

NO. Neither a Re-entry Permit, nor a green card (for trips taking less than one year), nor the "special immigrant" visa, will guarantee that a permanent resident will be readmitted to the U.S.

Remember: the immigration inspector at the port of entry always has the right to refuse entry to any permanent resident if he or she deems that the individual has either abandoned the intent to remain permanently in the U.S., or has committed a crime, or falls within one of the grounds for exclusion under U.S. immigration law.
