Last Is Least ???

 

Parshas Hashavua וישלח

אחרון אחרון חביב
Is last best or least?

It is customary when calling up the last speaker at a  function
to add at the introduction  "אחרון אחרון חביב".

It's done so, as to suggest that this כיבוד is a חשובע כיבוד 

It is also customary to honor special people with ברכה אחריתא.

 Is last, more of a כיבוד than the ones before?
 

The Gemoro  Gittin 60a & Shulchan Aruch O.Ch. 136 lists
whom to call up to the Torah after Kohen & Levi.

You start with the most חשובע person the Talmid Chacham
& Parnes until you get to the last two עליות 
**שישי* & שביעי where everyone even the simple Yidden
can be עולה.
 
According to the Gemoro and Shulchan Aruch,**שישי* & שביעי
the last two עליות are the least חשוב.

 

*The Zohar argues on the Bavli and considers Shishi as a Chashuva Aliya.

**The Mishna Verurah  (136 sk5) writes "Today the Minhag Is for the
Godol Hatzibur (The Rov etc.) to be mesayem the sidrah"  (takes שביעי)
