You are correct 6 months to fill a scheduled medication schedules 3 through 4 and 7 days for schedule 2 medications and 1 year for non narcotic prescriptions, now refills must also be dispensed for schedules 3 through 5 before the script expires. It is 100 percent illegal for a doctor at the federal level or a pharmacist to accept scripts that are post dated for any scheduled medications. In other words the doctor can't legally write them and the pharmacy can't hold the post dated scripts or fill them if they are aware or suspect that the doctor is doing this. I guess if you had a post dated schedule 2 script and held it then went to the pharmacy no the pharmacist wouldn't know this and possibly fill the prescription. The laws on scheduled medications can be found on the DEA website under the Controlled Substance Act and I believe the National Board of Pharmacist's website under prescribing laws.
