it's not that "in that" has a higher priority; it's that the confusion is a one-way street. i.e., most writers, and ALL speakers, of english commonly use "because" in situations where "in that" would be more appropriate. by contrast, it would be ridiculous to use "in that" in a situation that demands "because".
because of this imbalance, it's highly likely that a question whose answer choices feature both "because" and "in that"
should take "in that"; if "because" were the correct choice, then "in that" would sound absurd.
the same pattern is evident with "like" vs. "such as". most writers (and essentially all speakers) regularly use "like" in place of "such as", but not the other way around. therefore, if any confusion between "like" and "such as" is possible, then "such as" is almost certainly the correct alternative.
