IF "71" GTR "7000" yields true

According to my code, If %~1 is greater than 7000, go to ExceedError

IF "%~1" GTR "7000" GOTO ExceedError

Contents of ExceedError:

ECHO Value exceeded the maximum value. See help file.
EXIT /B

But this happened:

C:\modules>If "71" GTR "7000" GOTO ExceedError

C:\modules>Echo Value exceeded the maximum value. See help file.
Value exceeded the maximum value. See help file.

C:\modules>exit /b

What happened? Is there something wrong?
