Sort by Field

[KGodel]

I basically have three values I want excluded from the typical alphabetical sorting of ORDER BY. I want 2 values to be sorted first and one value to be sorted last. The others change so I just want them to have a normal sort between the 2 first values and the last value. Instead of:

A
B
C
...
Z

Where val1, val2, and val3 are included, I want:

val1
val2
A
B
C
...
Z
val3
