> Different UI styles use different triangle directions.
Of which one is correct (fat end of the triangle = direction where valuea are greater), and the other is wrong (triangle misinterpreted as an arrow). Launchpad uses the wrong one.
> From what I recall, the triangle is treated not as an arrow but as a visual representation of small to large.
Yes, what you describe is the correct convention, and if you spend a moment looking at how Launchpad behaves, you will see that it does the exact opposite.
The triangle is a triangle. The misconception that it is an arrow is intrinsically flawed, because if it were an arrow which points in a direction, you would need to know whether it is assumed that the direction of the arrow is the one in which values increase or decrease, hence you would need a second indicator.

> Launchpad's convention matches Ubuntu's
No more. Ubuntu's convention has been finally fixed. /bugs.launchpad .net/ubuntu/ +source/ ubuntu- themes/ +bug/901703

> which I believe matches the GTK default
It used to. GTK's default has been recognized upstream as a bug but recently "resolved" as WontFix because it would allegedly be "too much work". /bugzilla. gnome.org/ show_bug. cgi?id= 305277
