Yes, you could avoid temp with

  set -A "${${(P)1}[pages]}[2]" 50
  set -A "${${(P)1}[pages]}[3]" 100
  set -A "${${(P)1}[pages]}[4]" 150

but that's not as clear or easily maintainable.  You could also do

  temp=${${(P)1}[pages]}  # Note one less (P) and not an array
  set -A "${temp}[2]" 50
  set -A "${temp}[3]" 100
  set -A "${temp}[4]" 150

or even

  set -A "${temp}[2,4]" 50 100 150

All three of the above would avoid the need to write an entire array
back as the last step, but unless you're dealing with huge arrays the
best form is the one you understand.
