It's an input type dialog, which would return into the 'inputtext' variable (which is a string, not an integer).

Use this as it's a hell of a lot neater and your problem is fixed:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if(dialogid == 1 && response)
    {
      new age = strval(inputtext);
        if(strlen(inputtext) < 1 && !IsNumeric(inputtext))
        {
            SendClientMessage(playerid, COLOR_RED, "You must enter a numeric string!");
            ShowPlayerDialog(playerid, 1, DIALOG_STYLE_INPUT, "Please enter your characters age", "Please enter your characters' age!" , "Continue", "Cancel");
        }
        else
        {
          if(age < 120 || age >= 1)
          {
            new string[128];
            PlayerInfo[playerid][pAge] = age;
            format(string, sizeof(string), "Hooray! Your age has been set to %d!", age);
            SendClientMessage(playerid, COLOR_RED, string);
          }
          else
          {
                SendClientMessage(playerid, COLOR_RED, "You must enter an age, from between 1 to 120!");
                ShowPlayerDialog(playerid, 1, DIALOG_STYLE_INPUT, "Please enter your characters age", "Please enter your characters' age!" , "Continue", "Cancel");
          }
        }
    }
    return 1;
