I believe that p.value.log is actually referring to the log of the likelihood ratio test, whereas the p.value.sc is referring to the score log-rank test.
According to this: https://rdrr.io/cran/survival/src/R/summary.coxph.R the log LRT is stored in logtest while the log-rank is in sctest. Then when it goes through broom::glance, these are logged as p.value.log and p.value.sc respectively (https://github.com/tidymodels/broom/blob/main/R/survival-coxph-tidiers.R#L153-L155)
