The 12F629 does not have the OSCCON @ [8F - hex] , register so you can't set the speed it is stuck at 4MHz.
You will need to read the DATA SHEET a bit more closely -- as always it is buried in the fineprint
It's quite similar your chip configs to what i'm using. 12F683 seems like a nice little chip, but still for timing applications you need an external Xtal, INTRC its not enough after some days running.

What would be handy is how to configure the 12f629 to run in LP xtal mode AND make it work in picbasic. No problem if the pause periods run slower you can always compensate for that, but the chip refuses to work in LP
