It seems that in my above post I was recalling reg's from some other series! Either that or my brain has pieced together remnants from past decisions or explanations from some other kind of series organisers. Doh. Amyhowsy, the numerical order thing did apply in previous seasons but it no longer does.
My first part with regard to disrupted qualifying is probably close to unwritten custom and practice but might be way off fro F1. The second part regarding individuals not making the grid but given dispensation is essentially correct, although the sporting reg's are a tad more knadgery!
Excerpt from FIA F1 2014 Sporting Regulations:
QUOTE: 36) THE GRID
36.1 During Q1, any driver whose best qualifying lap exceeds 107% of the fastest time set during that session, or who fails to set a time, will not be allowed to take part in the race. Under exceptional circumstances however, which may include setting a suitable lap time in a free practice session, the stewards may permit the car to start the race.
Should there be more than one driver accepted in this manner, the grid order will be determined by the stewards.
36.2 a) The grid will be drawn up as follows :
i) The last eight positions will be occupied by the cars eliminated during Q1, the fastest in 19th position.
ii) The next eight positions will be occupied by the cars eliminated during Q2, the fastest in 11th position.
iii) The top ten positions will be occupied by the cars which took part in Q3, the fastest from the position on the grid which was the pole position in the previous year or, on a new circuit, has been designated as such by the FIA safety delegate.
If two or more drivers set identical times during Q1, Q2 or Q3 priority will be given to the one who set it first.
If less than 26 cars are entered in the Championship appropriate amendments will be made to the above in accordance with Article 33.1.
36.2 b) If more than one driver fails to set a time during Q1, Q2 or Q3 they will be arranged in the following order :
i) Any driver who attempted to set a qualifying time by starting a flying lap.
ii) Any driver who failed to start a flying lap.
iii) Any driver who failed to leave the pits during the period.
36.2 c) Once the grid has been established in accordance with a) and b) above, grid position penalties will be applied to the drivers in question in the order the offences were committed. If more than one driver incurs a penalty under Article 28.4(a) or Article 28.6(a) preference will be given to the driver whose team first informed the technical delegate that an engine or gearbox change will be carried out.
36.2 d) Any driver who incurs a penalty under Article 28.4(a) or Article 28.6(a) will take precedence over any driver whose qualifying times have been deleted for any reason.
If more than one driver falls into a single category in b) or d) above they will be arranged on the grid in the order they were classified in the previous period of qualifying or, in the case of Q1, the order they were classified in P3. END QUOTE
