Hmm … It looks like `temperature` was never exposed to RosettaScripts (despite the documentation saying it was). It also looks like the `task_operations` was inadvertantly omitted when we updated the RosettaScript syntax.
Both of these are bugs, and thanks for reporting them. We’ll try to get them fixed for future versions of Rosetta. (Unfortunately, without altering the C++ code and recompiling there’s no way of accessing them in Rosetta3.9.)
