Sort Options

I am adding the ability to sort Article Summaries on a page, but want to keep sorting simple.

Questions:
1.) Is it okay to combine Sort-Field and Sort-Order into one field?

2.) If so, which of these options is easiest to understand…

Option #1:

Sort by:


Date (Newest to Oldest)
Date (Oldest to Newst)
Title (A to Z)
Title (Z to A)
Rating (Highest to Lowest)
Rating (Lowest to Highest)

Option #2:

Sort by:


Date (Descending)
Date (Ascending)
Title (Ascending)
Title (Descending)
Rating (Descending)
Rating (Ascending)

Option #3:

Sort by:


Date (<insert down arrow here>)
Date (<insert up arrow here>)
Title (<insert up arrow here>)
Title (<insert down arrow here>)
Rating (<insert down arrow here>)
Rating (<insert up arrow here>)

Option #4:

Sort by:


Date (Newest 1st)
Date (Oldest 1st)
Title (A-to-Z)
Title (Z-to-A)
Rating (Highest 1st)
Rating (Lowest 1st)

Option #5:

Sort by:


Date (??)
Date (??)
Title (??)
Title (??)
Rating (??)
Rating (??)

190 views and no one has an opinion huh?

Would it be better if I broke things out into two separate fields like…


Sort by		Direction
--------	----------
Date		Ascending
Title		Descending
Rank

I figured users would appreciate only having to select one choice…

Sincerely,

Debbie

Option 1 + 3

Either two separate fields or if you take the single field approach then code it so that it can be used directly without needing to convert it - eg. date and date desc
