We don't typically tag scientific/technical terms as "rare" unless there exists a more common synonym.

Maybe only one sense. I think just [physics] is enough. The original 秩序度 entry was submitted by a physicist.

degree of order

長距離秩序度

In the case of binary alloys, a degree of order of atom species A and B increases with decreasing temperature after a substance undergoes a transition from a disordered phase to an ordered phase. The "long-range order parameter" means this degree of order. It can be measured from the intensity change of a specific reflection that appears in an ordered phase.

Degree of order:
異なる遷移金属原子が高い秩序度をもって配列したダブルペロブスカイト型酸化物を合成し
We have succeeded in synthesis of four new double-perovskite oxides, each of which exhibits high degree of order in the arrangements of different transition-metal atom

A bunch of other terms for this:
https://ja.wikipedia.org/wiki/秩序変数
秩序変数(ちつじょへんすう、英: order parameter)または秩序パラメータ、オーダーパラメータとは、相が持つ秩序を表すマクロな変数のことである。

秩序変数	765	42.7%  <--- wikipedia headword for "order parameter"
秩序パラメータ	350	19.5%
オーダーパラメータ	222	12.4%

秩序度	454	25.3% <--- this term

This can mean "high degree of order" in any context (philosophy was one I found in book results).  Even in a chemistry context, it doesn't appear to always be "order parameter".  So the ngrams are inflated vs. other glosses of "order parameter".

For "order parameter", this often appears as a suffix:
配向秩序度	70	100.0%  sometimes just "order parameter", or "orientation order parameter"
長距離秩序度	0	0.0% long-range order parameter
短距離秩序度	0	0.0% short-range order parameter
