I forget which schools look at the scaled score as a few do, but the percentile score is the most common in PharmCAS schools.
In general, getting a score between the 75th and 85th percentile or above that range is considered competitive (at or above average) for most schools. A 70 is okay, but it won't help your application any and could be frowned upon by some people. Any score below the 70th percentile becomes a liability on your application that needs to be balanced out with a good GPA, interview, and/or experience record.
In general, schools seem more forgiving for people with higher GPAs but lower PCATs. There have been success stories here where people have got in with a 70 or lower PCAT. However, I would have retaken the PCAT had I gotten less than an 80th percentile given that my GPA had been average with a slightly downward trend.
