By comparison:
PLT 299.100 and scsh 0.6.6 return (2 2).
JScheme 7.1 and sisc 1.9.7 return (2 1).

Hi, I have recently stumbled upon various bugs in my code
because the order of the evaluation of the elements in a quasiquote

Changes how? Can you give us an example, to make things concrete?
Sorry, this is the stripped down version of the cause of the bug I'm
finding various places:
(let ((a 1))
`( ,(begin (set! a 2) a)
,a))
-> (2 1)
Wouldn't it be better if this one returned (2 2)?
