I'm a current PGY4 in the field. While PM&R competitiveness is no longer in the "accept if they have a heartbeat and speak English," if you apply broadly you should find a position. However, it is really important to apply broadly, as this past match only one position went unfilled. We're a very competitive field by percentage of US MD/DO applicants to apply and end up matching (usually 89-93% of US seniors match), but we're quite noncompetitive when it comes to scores (I think we're second lowest after FM).
Remediating two core clerkships is a red flag--that means you'll have to have a good explanation no matter what specialty you apply into. And with a field like PM&R that while less competitive, but small with limited # of positions, I would recommend applying very broadly if your goal is to not end up at a "bottom rung" program. Your board scores are roughly average for the field, so they won't help you stand out much (they won't hurt you either), and if I were in your shoes I'd apply to every PM&R program you'd be willing to go to. If you end up getting too many interviews is easy to cancel--it's much harder to get more interviews if you apply to too few places. I would recommend that for anyone with any red flags (failed clerkships, failed boards, graduated off-cycle, etc. etc.)
It does help a bit (or rather, hurt less) that the two clerkships were OB and peds, rather than IM and PM&R, but a remediated clerkship is a remediated clerkship.
Things like research will help out if you have any, as will proven dedication to the field, and honestly, even your demeanor. In fields that are less competitive like psych, FM, PM&R, etc., how well you communicate with others and how well you get along with them can't be understated. We really are a specialty that relies on a multidisciplinary team. Plus, most PM&R programs are smaller, so they will tend to look for applicants that can work well with the current group of residents (which is why many places have a "feel" to them, though this is partially self-selecting on the part of the applicant as well)
I've met/known a number of people with a failed board score or clerkship who has matched to PM&R, so it's definitely doable.
Feel free to PM me if you have any specific questions.
