From "Series 32000 Instruction Set Reference Manual", Section 6.2
(General Interrupt/Trap Sequence):
... the PSR is then set to reflect Supervisor Mode, and the selection
of the Interrupt Stack.

It is kind of logical, too. I've never seen a machine that didn't
switch to supervisor mode on an interrupt (ok, on the PDP-11 you
can choose, but still.....)
