Even for a small empire, I still believe Order is better. Let's do some turn-by-turn calculations assuming that the Order bonus is 100 bpt and the Freedom bonus is 150 bpt. 1 social policy per 10 turns(average CV culture rate). 8 GS stored to bulb after research labs. Turn 250 victory.
If you can get Planned Economy at turn 180(I have never gotten it that early, but with better culture I suppose you could), then you would get 7000 bpt from the 70 turns and 6400 beakers from the 8 bulbs. That's a total of 13,400 beakers.
If you finish Freedom at turn 210(3 more policies than Planned Economy), then you'd get 6000 beakers from the 40 turns and 9600 beakers from the 8 bulbs. That's a total of 15,600 beakers.
If you finish Planned Economy and Scholasticism at turn 220(1 more policy than Freedom), then you would get the 13,400 beakers from finishing PE at turn 180, 1500 beakers from finishing Scholasticism with 30 turns to go(assuming it gives 50 bpt. No idea what it gives, could use some real values), and another 3200 beakers from the 8 bulbs. That's a total of 18,100 beakers.
Now personally, I've never done better than full Tradition, full Rationalism, Planned Economy, and Aesthetics. But I assume that with enough culture pushing, these turn times could be achievable. Obviously the slower your culture, the less impact Freedom will have on your finish time. You could get an additional 13,400 beakers by getting 14 policies(including openers), 15,600 beaker by getting 18 policies, or 18,100 beakers by getting 19 policies. If you can't open Rationalism immediately after finishing Tradition/Liberty in either the Planned Economy or Freedom path, then you would need an additional policy for both of them.
If I made any math mistakes, please let me know

. And some comment on how many bpt Scholasticism gives would be appreciated. I have only gotten it a few times and I'm basing my values off of a vague memory.
