2 degC betwwen cores doesn't sound too much, also considering param spread
etc. The ACPI value comes from other module - might be an average, and the
acpi module might use a different formula and/or different params (the
coretemp is likely more correct, being very hw-specific).

120+ degC actual silicon T isn't uncommon as max operating T. 100 degC 
is likely a derating which allows for a reasonable margin before the 
chip goes out of spec. Physical damage occurs at quite higher T.
Of course, don't expect much long-term reliabilty if you keep your chips
close to that limit for long time (or better, with high duty-ratio).
