Scoreboard and count arguments do not work correctly when combined

When using this command in a command block:
/say @a[score_NAME_min=0,c=1]

The name should be the player at the top of the scoreboard

{which can be seen when the scoreboard is set to the sidebar}

When the command is run, the arguments do not "talk to each other" and just act as separate arguments. When using @a[c=1] the command will list the closest player to the command block. When using @a[score_NAME_min=0,c=1] the command should list the player at the top of the scoreboard list

{shown by setting the scoreboard to the sidebar}

but instead shows the closest player to the command block with the score.

The command should say the player with the highest score, which is at the top of the scoreboard list (shown by looking at the sidebar).
