Tone,
First off, you've implicitly admitted that metros work out better for higher scoring games... the main point.
Second, if you read SirPleb's thread, I think you can see him have a sort of uncomfortable feeling about warring with some of the Sid AIs at points. Also, the quicker a player a pounces on the AI, the more territory that player has for more turns of the game. SirPleb writes "The scoring works by averaging your per-turn scores throughout the game. For each turn a (hidden) per-turn score is calculated as:
(Territory + HappyCitizens*2 + ContentCitizens + Specialists) * Difficulty
The total of all your per-turn scores is divided by the number of turns played so far to get your actual game score. I.e. your actual score is the average of your per-turn scores." Later in the article he writes
"To maximize score you want to maximize territory, population, and happiness. And you want to maximize them as early as possible. The earlier you add each increase to your per-turn score, the more impact that increase will have on the averaged result which becomes your actual score."
So, in response to your question "The question is why did they space that way?" the response seems to come out something like "to crush the AIs as quickly as possible and maximize territory as quickly as possible."
To the second question "Was it to be the most effective in beating the AI?", the answer seems to come out "yes."
Here's SirPleb's article on maximizing score:
